+# easyjson [![Build Status](https://travis-ci.org/mailru/easyjson.svg?branch=master)](https://travis-ci.org/mailru/easyjson) [![Go Report Card](https://goreportcard.com/badge/github.com/mailru/easyjson)](https://goreportcard.com/report/github.com/mailru/easyjson)
+
+Package easyjson provides a fast and easy way to marshal/unmarshal Go structs
+to/from JSON without the use of reflection. In performance tests, easyjson
+outperforms the standard `encoding/json` package by a factor of 4-5x, and other
+JSON encoding packages by a factor of 2-3x.
+
+easyjson aims to keep generated Go code simple enough so that it can be easily
+optimized or fixed. Another goal is to provide users with the ability to
+customize the generated code by providing options not available with the
+standard `encoding/json` package, such as generating "snake_case" names or
+enabling `omitempty` behavior by default.
+
+## Usage
+```sh
+# install
+go get -u github.com/mailru/easyjson/...
+
+# run
+easyjson -all <file>.go
+```
+
+The above will generate `<file>_easyjson.go` containing the appropriate marshaler and
+unmarshaler funcs for all structs contained in `<file>.go`.
+
+Please note that easyjson requires a full Go build environment and the `GOPATH`
+environment variable to be set. This is because easyjson code generation
+invokes `go run` on a temporary file (an approach to code generation borrowed
+from [ffjson](https://github.com/pquerna/ffjson)).
+
+## Options
+```txt
+Usage of easyjson:
+  -all
+    	generate marshaler/unmarshalers for all structs in a file
+  -build_tags string
+    	build tags to add to generated file
+  -leave_temps
+    	do not delete temporary files
+  -no_std_marshalers
+    	don't generate MarshalJSON/UnmarshalJSON funcs
+  -noformat
+    	do not run 'gofmt -w' on output file
+  -omit_empty
+    	omit empty fields by default
+  -output_filename string
+    	specify the filename of the output
+  -pkg
+    	process the whole package instead of just the given file
+  -snake_case
+    	use snake_case names instead of CamelCase by default
+  -lower_camel_case
+        use lowerCamelCase instead of CamelCase by default
+  -stubs
+    	only generate stubs for marshaler/unmarshaler funcs
+  -disallow_unknown_fields
+        return error if some unknown field in json appeared
+```
+
+Using `-all` will generate marshalers/unmarshalers for all Go structs in the
+file. If `-all` is not provided, then only those structs whose preceding
+comment starts with `easyjson:json` will have marshalers/unmarshalers
+generated. For example:
+
+```go
+//easyjson:json
+type A struct {}
+```
+
+Additional option notes:
+
+* `-snake_case` tells easyjson to generate snake\_case field names by default
+  (unless overridden by a field tag). The CamelCase to snake\_case conversion
+  algorithm should work in most cases (ie, HTTPVersion will be converted to
+  "http_version").
+
+* `-build_tags` will add the specified build tags to generated Go sources.
+
+## Generated Marshaler/Unmarshaler Funcs
+
+For Go struct types, easyjson generates the funcs `MarshalEasyJSON` /
+`UnmarshalEasyJSON` for marshaling/unmarshaling JSON. In turn, these satisify
+the `easyjson.Marshaler` and `easyjson.Unmarshaler` interfaces and when used in
+conjunction with `easyjson.Marshal` / `easyjson.Unmarshal` avoid unnecessary
+reflection / type assertions during marshaling/unmarshaling to/from JSON for Go
+structs.
+
+easyjson also generates `MarshalJSON` and `UnmarshalJSON` funcs for Go struct
+types compatible with the standard `json.Marshaler` and `json.Unmarshaler`
+interfaces. Please be aware that using the standard `json.Marshal` /
+`json.Unmarshal` for marshaling/unmarshaling will incur a significant
+performance penalty when compared to using `easyjson.Marshal` /
+`easyjson.Unmarshal`.
+
+Additionally, easyjson exposes utility funcs that use the `MarshalEasyJSON` and
+`UnmarshalEasyJSON` for marshaling/unmarshaling to and from standard readers
+and writers. For example, easyjson provides `easyjson.MarshalToHTTPResponseWriter`
+which marshals to the standard `http.ResponseWriter`. Please see the [GoDoc
+listing](https://godoc.org/github.com/mailru/easyjson) for the full listing of
+utility funcs that are available.
+
+## Controlling easyjson Marshaling and Unmarshaling Behavior
+
+Go types can provide their own `MarshalEasyJSON` and `UnmarshalEasyJSON` funcs
+that satisify the `easyjson.Marshaler` / `easyjson.Unmarshaler` interfaces.
+These will be used by `easyjson.Marshal` and `easyjson.Unmarshal` when defined
+for a Go type.
+
+Go types can also satisify the `easyjson.Optional` interface, which allows the
+type to define its own `omitempty` logic.
+
+## Type Wrappers
+
+easyjson provides additional type wrappers defined in the `easyjson/opt`
+package. These wrap the standard Go primitives and in turn satisify the
+easyjson interfaces.
+
+The `easyjson/opt` type wrappers are useful when needing to distinguish between
+a missing value and/or when needing to specifying a default value. Type
+wrappers allow easyjson to avoid additional pointers and heap allocations and
+can significantly increase performance when used properly.
+
+## Memory Pooling
+
+easyjson uses a buffer pool that allocates data in increasing chunks from 128
+to 32768 bytes. Chunks of 512 bytes and larger will be reused with the help of
+`sync.Pool`. The maximum size of a chunk is bounded to reduce redundant memory
+allocation and to allow larger reusable buffers.
+
+easyjson's custom allocation buffer pool is defined in the `easyjson/buffer`
+package, and the default behavior pool behavior can be modified (if necessary)
+through a call to `buffer.Init()` prior to any marshaling or unmarshaling.
+Please see the [GoDoc listing](https://godoc.org/github.com/mailru/easyjson/buffer)
+for more information.
+
+## Issues, Notes, and Limitations
+
+* easyjson is still early in its development. As such, there are likely to be
+  bugs and missing features when compared to `encoding/json`. In the case of a
+  missing feature or bug, please create a GitHub issue. Pull requests are
+  welcome!
+
+* Unlike `encoding/json`, object keys are case-sensitive. Case-insensitive
+  matching is not currently provided due to the significant performance hit
+  when doing case-insensitive key matching. In the future, case-insensitive
+  object key matching may be provided via an option to the generator.
+
+* easyjson makes use of `unsafe`, which simplifies the code and
+  provides significant performance benefits by allowing no-copy
+  conversion from `[]byte` to `string`. That said, `unsafe` is used
+  only when unmarshaling and parsing JSON, and any `unsafe` operations
+  / memory allocations done will be safely deallocated by
+  easyjson. Set the build tag `easyjson_nounsafe` to compile it
+  without `unsafe`.
+
+* easyjson is compatible with Google App Engine. The `appengine` build
+  tag (set by App Engine's environment) will automatically disable the
+  use of `unsafe`, which is not allowed in App Engine's Standard
+  Environment. Note that the use with App Engine is still experimental.
+
+* Floats are formatted using the default precision from Go's `strconv` package.
+  As such, easyjson will not correctly handle high precision floats when
+  marshaling/unmarshaling JSON. Note, however, that there are very few/limited
+  uses where this behavior is not sufficient for general use. That said, a
+  different package may be needed if precise marshaling/unmarshaling of high
+  precision floats to/from JSON is required.
+
+* While unmarshaling, the JSON parser does the minimal amount of work needed to
+  skip over unmatching parens, and as such full validation is not done for the
+  entire JSON value being unmarshaled/parsed.
+
+* Currently there is no true streaming support for encoding/decoding as
+  typically for many uses/protocols the final, marshaled length of the JSON
+  needs to be known prior to sending the data. Currently this is not possible
+  with easyjson's architecture.
+  
+* easyjson parser and codegen based on reflection, so it wont works on `package main` 
+  files, because they cant be imported by parser.
+
+## Benchmarks
+
+Most benchmarks were done using the example
+[13kB example JSON](https://dev.twitter.com/rest/reference/get/search/tweets)
+(9k after eliminating whitespace). This example is similar to real-world data,
+is well-structured, and contains a healthy variety of different types, making
+it ideal for JSON serialization benchmarks.
+
+Note:
+
+* For small request benchmarks, an 80 byte portion of the above example was
+  used.
+
+* For large request marshaling benchmarks, a struct containing 50 regular
+  samples was used, making a ~500kB output JSON.
+
+* Benchmarks are showing the results of easyjson's default behaviour,
+  which makes use of `unsafe`.
+
+Benchmarks are available in the repository and can be run by invoking `make`.
+
+### easyjson vs. encoding/json
+
+easyjson is roughly 5-6 times faster than the standard `encoding/json` for
+unmarshaling, and 3-4 times faster for non-concurrent marshaling. Concurrent
+marshaling is 6-7x faster if marshaling to a writer.
+
+### easyjson vs. ffjson
+
+easyjson uses the same approach for JSON marshaling as
+[ffjson](https://github.com/pquerna/ffjson), but takes a significantly
+different approach to lexing and parsing JSON during unmarshaling. This means
+easyjson is roughly 2-3x faster for unmarshaling and 1.5-2x faster for
+non-concurrent unmarshaling.
+
+As of this writing, `ffjson` seems to have issues when used concurrently:
+specifically, large request pooling hurts `ffjson`'s performance and causes
+scalability issues. These issues with `ffjson` can likely be fixed, but as of
+writing remain outstanding/known issues with `ffjson`.
+
+easyjson and `ffjson` have similar performance for small requests, however
+easyjson outperforms `ffjson` by roughly 2-5x times for large requests when
+used with a writer.
+
+### easyjson vs. go/codec
+
+[go/codec](https://github.com/ugorji/go) provides
+compile-time helpers for JSON generation. In this case, helpers do not work
+like marshalers as they are encoding-independent.
+
+easyjson is generally 2x faster than `go/codec` for non-concurrent benchmarks
+and about 3x faster for concurrent encoding (without marshaling to a writer).
+
+In an attempt to measure marshaling performance of `go/codec` (as opposed to
+allocations/memcpy/writer interface invocations), a benchmark was done with
+resetting length of a byte slice rather than resetting the whole slice to nil.
+However, the optimization in this exact form may not be applicable in practice,
+since the memory is not freed between marshaling operations.
+
+### easyjson vs 'ujson' python module
+
+[ujson](https://github.com/esnme/ultrajson) is using C code for parsing, so it
+is interesting to see how plain golang compares to that. It is imporant to note
+that the resulting object for python is slower to access, since the library
+parses JSON object into dictionaries.
+
+easyjson is slightly faster for unmarshaling and 2-3x faster than `ujson` for
+marshaling.
+
+### Benchmark Results
+
+`ffjson` results are from February 4th, 2016, using the latest `ffjson` and go1.6.
+`go/codec` results are from March 4th, 2016, using the latest `go/codec` and go1.6.

+# Elastic 3.0
+
+Elasticsearch 2.0 comes with some [breaking changes](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/breaking-changes-2.0.html). You will probably need to upgrade your application and/or rewrite part of it due to those changes.
+
+We use that window of opportunity to also update Elastic (the Go client) from version 2.0 to 3.0. This will introduce both changes due to the Elasticsearch 2.0 update as well as changes that make Elastic cleaner by removing some old cruft.
+
+So, to summarize:
+
+1. Elastic 2.0 is compatible with Elasticsearch 1.7+ and is still actively maintained.
+2. Elastic 3.0 is compatible with Elasticsearch 2.0+ and will soon become the new master branch.
+
+The rest of the document is a list of all changes in Elastic 3.0.
+
+## Pointer types
+
+All types have changed to be pointer types, not value types. This not only is cleaner but also simplifies the API as illustrated by the following example:
+
+Example for Elastic 2.0 (old):
+
+```go
+q := elastic.NewMatchAllQuery()
+res, err := elastic.Search("one").Query(&q).Do()  // notice the & here
+```
+
+Example for Elastic 3.0 (new):
+
+```go
+q := elastic.NewMatchAllQuery()
+res, err := elastic.Search("one").Query(q).Do()   // no more &
+// ... which can be simplified as:
+res, err := elastic.Search("one").Query(elastic.NewMatchAllQuery()).Do()
+```
+
+It also helps to prevent [subtle issues](https://github.com/olivere/elastic/issues/115#issuecomment-130753046).
+
+## Query/filter merge
+
+One of the biggest changes in Elasticsearch 2.0 is the [merge of queries and filters](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_query_dsl_changes.html#_queries_and_filters_merged). In Elasticsearch 1.x, you had a whole range of queries and filters that were basically identical (e.g. `term_query` and `term_filter`).
+
+The practical aspect of the merge is that you can now basically use queries where once you had to use filters instead. For Elastic 3.0 this means: We could remove a whole bunch of files. Yay!
+
+Notice that some methods still come by "filter", e.g. `PostFilter`. However, they accept a `Query` now when they used to accept a `Filter` before.
+
+Example for Elastic 2.0 (old):
+
+```go
+q := elastic.NewMatchAllQuery()
+f := elastic.NewTermFilter("tag", "important")
+res, err := elastic.Search().Index("one").Query(&q).PostFilter(f)
+```
+
+Example for Elastic 3.0 (new):
+
+```go
+q := elastic.NewMatchAllQuery()
+f := elastic.NewTermQuery("tag", "important") // it's a query now!
+res, err := elastic.Search().Index("one").Query(q).PostFilter(f)
+```
+
+## Facets are removed
+
+[Facets have been removed](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_removed_features.html#_facets_have_been_removed) in Elasticsearch 2.0. You need to use aggregations now.
+
+## Errors
+
+Elasticsearch 2.0 returns more information about an error in the HTTP response body. Elastic 3.0 now reads this information and makes it accessible by the consumer.
+
+Errors and all its details are now returned in [`Error`](https://github.com/olivere/elastic/blob/release-branch.v3/errors.go#L59).
+
+### HTTP Status 404 (Not Found)
+
+When Elasticsearch does not find an entity or an index, it generally returns HTTP status code 404. In Elastic 2.0 this was a valid result and didn't raise an error from the `Do` functions. This has now changed in Elastic 3.0.
+
+Starting with Elastic 3.0, there are only two types of responses considered successful. First, responses with HTTP status codes [200..299]. Second, HEAD requests which return HTTP status 404. The latter is used by Elasticsearch to e.g. check for existence of indices or documents. All other responses will return an error.
+
+To check for HTTP Status 404 (with non-HEAD requests), e.g. when trying to get or delete a missing document, you can use the [`IsNotFound`](https://github.com/olivere/elastic/blob/release-branch.v3/errors.go#L84) helper (see below).
+
+The following example illustrates how to check for a missing document in Elastic 2.0 and what has changed in 3.0.
+
+Example for Elastic 2.0 (old):
+
+```go
+res, err = client.Get().Index("one").Type("tweet").Id("no-such-id").Do()
+if err != nil {
+  // Something else went wrong (but 404 is NOT an error in Elastic 2.0)
+}
+if !res.Found {
+	// Document has not been found
+}
+```
+
+Example for Elastic 3.0 (new):
+
+```go
+res, err = client.Get().Index("one").Type("tweet").Id("no-such-id").Do()
+if err != nil {
+  if elastic.IsNotFound(err) {
+    // Document has not been found
+  } else {
+    // Something else went wrong
+  }
+}
+```
+
+### HTTP Status 408 (Timeouts)
+
+Elasticsearch now responds with HTTP status code 408 (Timeout) when a request fails due to a timeout. E.g. if you specify a timeout with the Cluster Health API, the HTTP response status will be 408 if the timeout is raised. See [here](https://github.com/elastic/elasticsearch/commit/fe3179d9cccb569784434b2135ca9ae13d5158d3) for the specific commit to the Cluster Health API.
+
+To check for HTTP Status 408, we introduced the [`IsTimeout`](https://github.com/olivere/elastic/blob/release-branch.v3/errors.go#L101) helper.
+
+Example for Elastic 2.0 (old):
+
+```go
+health, err := client.ClusterHealth().WaitForStatus("yellow").Timeout("1s").Do()
+if err != nil {
+  // ...
+}
+if health.TimedOut {
+  // We have a timeout
+}
+```
+
+Example for Elastic 3.0 (new):
+
+```go
+health, err := client.ClusterHealth().WaitForStatus("yellow").Timeout("1s").Do()
+if elastic.IsTimeout(err) {
+  // We have a timeout
+}
+```
+
+### Bulk Errors
+
+The error response of a bulk operation used to be a simple string in Elasticsearch 1.x.
+In Elasticsearch 2.0, it returns a structured JSON object with a lot more details about the error.
+These errors are now captured in an object of type [`ErrorDetails`](https://github.com/olivere/elastic/blob/release-branch.v3/errors.go#L59) which is used in [`BulkResponseItem`](https://github.com/olivere/elastic/blob/release-branch.v3/bulk.go#L206).
+
+### Removed specific Elastic errors
+
+The specific error types `ErrMissingIndex`, `ErrMissingType`, and `ErrMissingId` have been removed. They were only used by `DeleteService` and are replaced by a generic error message.
+
+## Numeric types
+
+Elastic 3.0 has settled to use `float64` everywhere. It used to be a mix of `float32` and `float64` in Elastic 2.0. E.g. all boostable queries in Elastic 3.0 now have a boost type of `float64` where it used to be `float32`.
+
+## Pluralization
+
+Some services accept zero, one or more indices or types to operate on.
+E.g. in the `SearchService` accepts a list of zero, one, or more indices to
+search and therefor had a func called `Index(index string)` and a func
+called `Indices(indices ...string)`.
+
+Elastic 3.0 now only uses the singular form that, when applicable, accepts a
+variadic type. E.g. in the case of the `SearchService`, you now only have
+one func with the following signature: `Index(indices ...string)`.
+
+Notice this is only limited to `Index(...)` and `Type(...)`. There are other
+services with variadic functions. These have not been changed.
+
+## Multiple calls to variadic functions
+
+Some services with variadic functions have cleared the underlying slice when
+called while other services just add to the existing slice. This has now been
+normalized to always add to the underlying slice.
+
+Example for Elastic 2.0 (old):
+
+```go
+// Would only cleared scroll id "two"
+// because ScrollId cleared the values when called multiple times
+client.ClearScroll().ScrollId("one").ScrollId("two").Do()
+```
+
+Example for Elastic 3.0 (new):
+
+```go
+// Now (correctly) clears both scroll id "one" and "two"
+// because ScrollId no longer clears the values when called multiple times
+client.ClearScroll().ScrollId("one").ScrollId("two").Do()
+```
+
+## Ping service requires URL
+
+The `Ping` service raised some issues because it is different from all
+other services. If not explicitly given a URL, it always pings `127.0.0.1:9200`.
+
+Users expected to ping the cluster, but that is not possible as the cluster
+can be a set of many nodes: So which node do we ping then?
+
+To make it more clear, the `Ping` function on the client now requires users
+to explicitly set the URL of the node to ping.
+
+## Meta fields
+
+Many of the meta fields e.g. `_parent` or `_routing` are now
+[part of the top-level of a document](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_mapping_changes.html#migration-meta-fields)
+and are no longer returned as parts of the `fields` object. We had to change
+larger parts of e.g. the `Reindexer` to get it to work seamlessly with Elasticsearch 2.0.
+
+Notice that all stored meta-fields are now [returned by default](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_crud_and_routing_changes.html#_all_stored_meta_fields_returned_by_default).
+
+## HasParentQuery / HasChildQuery
+
+`NewHasParentQuery` and `NewHasChildQuery` must now include both parent/child type and query. It is now in line with the Java API.
+
+Example for Elastic 2.0 (old):
+
+```go
+allQ := elastic.NewMatchAllQuery()
+q := elastic.NewHasChildFilter("tweet").Query(&allQ)
+```
+
+Example for Elastic 3.0 (new):
+
+```go
+q := elastic.NewHasChildQuery("tweet", elastic.NewMatchAllQuery())
+```
+
+## SetBasicAuth client option
+
+You can now tell Elastic to pass HTTP Basic Auth credentials with each request. In previous versions of Elastic you had to set up your own `http.Transport` to do this. This should make it more convenient to use Elastic in combination with [Shield](https://www.elastic.co/products/shield) in its [basic setup](https://www.elastic.co/guide/en/shield/current/enable-basic-auth.html).
+
+Example:
+
+```go
+client, err := elastic.NewClient(elastic.SetBasicAuth("user", "secret"))
+if err != nil {
+  log.Fatal(err)
+}
+```
+
+## Delete-by-Query API
+
+The Delete-by-Query API is [a plugin now](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_removed_features.html#_delete_by_query_is_now_a_plugin). It is no longer core part of Elasticsearch. You can [install it as a plugin as described here](https://www.elastic.co/guide/en/elasticsearch/plugins/2.0/plugins-delete-by-query.html).
+
+Elastic 3.0 still contains the `DeleteByQueryService`, but you need to install the plugin first. If you don't install it and use `DeleteByQueryService` you will most probably get a 404.
+
+An older version of this document stated the following:
+
+> Elastic 3.0 still contains the `DeleteByQueryService` but it will fail with `ErrPluginNotFound` when the plugin is not installed.
+>
+> Example for Elastic 3.0 (new):
+>
+> ```go
+> _, err := client.DeleteByQuery().Query(elastic.NewTermQuery("client", "1")).Do()
+> if err == elastic.ErrPluginNotFound {
+> 	// Delete By Query API is not available
+> }
+> ```
+
+I have decided that this is not a good way to handle the case of a missing plugin. The main reason is that with this logic, you'd always have to check if the plugin is missing in case of an error. This is not only slow, but it also puts logic into a service where it should really be just opaque and return the response of Elasticsearch.
+
+If you rely on certain plugins to be installed, you should check on startup. That's where the following two helpers come into play.
+
+## HasPlugin and SetRequiredPlugins
+
+Some of the core functionality of Elasticsearch has now been moved into plugins. E.g. the Delete-by-Query API is [a plugin now](https://www.elastic.co/guide/en/elasticsearch/plugins/2.0/plugins-delete-by-query.html).
+
+You need to make sure to add these plugins to your Elasticsearch installation to still be able to use the `DeleteByQueryService`. You can test this now with the `HasPlugin(name string)` helper in the client.
+
+Example for Elastic 3.0 (new):
+
+```go
+err, found := client.HasPlugin("delete-by-query")
+if err == nil && found {
+	// ... Delete By Query API is available
+}
+```
+
+To simplify this process, there is now a `SetRequiredPlugins` helper that can be passed as an option func when creating a new client. If the plugin is not installed, the client wouldn't be created in the first place.
+
+```go
+// Will raise an error if the "delete-by-query" plugin is NOT installed
+client, err := elastic.NewClient(elastic.SetRequiredPlugins("delete-by-query"))
+if err != nil {
+  log.Fatal(err)
+}
+```
+
+Notice that there also is a way to define [mandatory plugins](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-plugins.html#_mandatory_plugins) in the Elasticsearch configuration file.
+
+## Common Query has been renamed to Common Terms Query
+
+The `CommonQuery` has been renamed to `CommonTermsQuery` to be in line with the [Java API](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_java_api_changes.html#_query_filter_refactoring).
+
+## Remove `MoreLikeThis` and `MoreLikeThisField`
+
+The More Like This API and the More Like This Field query [have been removed](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_query_dsl_changes.html#_more_like_this) and replaced with the `MoreLikeThisQuery`.
+
+## Remove Filtered Query
+
+With the merge of queries and filters, the [filtered query became deprecated](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_query_dsl_changes.html#_literal_filtered_literal_query_and_literal_query_literal_filter_deprecated). While it is only deprecated and therefore still available in Elasticsearch 2.0, we have decided to remove it from Elastic 3.0. Why? Because we think that when you're already forced to rewrite many of your application code, it might be a good chance to get rid of things that are deprecated as well. So you might simply change your filtered query with a boolean query as [described here](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_query_dsl_changes.html#_literal_filtered_literal_query_and_literal_query_literal_filter_deprecated).
+
+## Remove FuzzyLikeThis and FuzzyLikeThisField
+
+Both have been removed from Elasticsearch 2.0 as well.
+
+## Remove LimitFilter
+
+The `limit` filter is [deprecated in Elasticsearch 2.0](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_query_dsl_changes.html#_literal_limit_literal_filter_deprecated) and becomes a no-op. Now is a good chance to remove it from your application as well. Use the `terminate_after` parameter in your search [as described here](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/search-request-body.html) to achieve similar effects.
+
+## Remove `_cache` and `_cache_key` from filters
+
+Both have been [removed from Elasticsearch 2.0 as well](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_query_dsl_changes.html#_filter_auto_caching).
+
+## Partial fields are gone
+
+Partial fields are [removed in Elasticsearch 2.0](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/_search_changes.html#_partial_fields) in favor of [source filtering](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/search-request-source-filtering.html).
+
+## Scripting
+
+A [`Script`](https://github.com/olivere/elastic/blob/release-branch.v3/script.go) type has been added to Elastic 3.0. In Elastic 2.0, there were various places (e.g. aggregations) where you could just add the script as a string, specify the scripting language, add parameters etc. With Elastic 3.0, you should now always use the `Script` type.
+
+Example for Elastic 2.0 (old):
+
+```go
+update, err := client.Update().Index("twitter").Type("tweet").Id("1").
+	Script("ctx._source.retweets += num").
+	ScriptParams(map[string]interface{}{"num": 1}).
+	Upsert(map[string]interface{}{"retweets": 0}).
+	Do()
+```
+
+Example for Elastic 3.0 (new):
+
+```go
+update, err := client.Update().Index("twitter").Type("tweet").Id("1").
+	Script(elastic.NewScript("ctx._source.retweets += num").Param("num", 1)).
+	Upsert(map[string]interface{}{"retweets": 0}).
+	Do()
+```
+
+## Cluster State
+
+The combination of `Metric(string)` and `Metrics(...string)` has been replaced by a single func with the signature `Metric(...string)`.
+
+## Unexported structs in response
+
+Services generally return a typed response from a `Do` func. Those structs are exported so that they can be passed around in your own application. In Elastic 3.0 however, we changed that (most) sub-structs are now unexported, meaning: You can only pass around the whole response, not sub-structures of it. This makes it easier for restructuring responses according to the Elasticsearch API. See [`ClusterStateResponse`](https://github.com/olivere/elastic/blob/release-branch.v3/cluster_state.go#L182) as an example.
+
+## Add offset to Histogram aggregation
+
+Histogram aggregations now have an [offset](https://github.com/elastic/elasticsearch/pull/9505) option.
+
+## Services
+
+### REST API specification
+
+As you might know, Elasticsearch comes with a REST API specification. The specification describes the endpoints in a JSON structure.
+
+Most services in Elastic predated the REST API specification. We are in the process of bringing all these services in line with the specification. Services can be generated by `go generate` (not 100% automatic though). This is an ongoing process.
+
+This probably doesn't mean a lot to you. However, you can now be more confident that Elastic supports all features that the REST API specification describes.
+
+At the same time, the file names of the services are renamed to match the REST API specification naming.
+
+### REST API Test Suite
+
+The REST API specification of Elasticsearch comes along with a test suite that official clients typically use to test for conformance. Up until now, Elastic didn't run this test suite. However, we are in the process of setting up infrastructure and tests to match this suite as well.
+
+This process in not completed though.

+# Changes in Elastic 5.0
+
+## Enforce context.Context in PerformRequest and Do
+
+We enforce the usage of `context.Context` everywhere you execute a request.
+You need to change all your `Do()` calls to pass a context: `Do(ctx)`.
+This enables automatic request cancelation and many other patterns.
+
+If you don't need this, simply pass `context.TODO()` or `context.Background()`.
+
+## Warmers removed
+
+Warmers are no longer necessary and have been [removed in ES 5.0](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_index_apis.html#_warmers).
+
+## Optimize removed
+
+Optimize was deprecated in ES 2.0 and has been [removed in ES 5.0](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_rest_api_changes.html#_literal__optimize_literal_endpoint_removed).
+Use [Force Merge](https://www.elastic.co/guide/en/elasticsearch/reference/master/indices-forcemerge.html) instead.
+
+## Missing Query removed
+
+The `missing` query has been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/master/query-dsl-exists-query.html#_literal_missing_literal_query).
+Use `exists` query with `must_not` in `bool` query instead.
+
+## And Query removed
+
+The `and` query has been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_search_changes.html#_deprecated_queries_removed).
+Use `must` clauses in a `bool` query instead.
+
+## Not Query removed
+
+TODO Is it removed?
+
+## Or Query removed
+
+The `or` query has been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_search_changes.html#_deprecated_queries_removed).
+Use `should` clauses in a `bool` query instead.
+
+## Filtered Query removed
+
+The `filtered` query has been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_search_changes.html#_deprecated_queries_removed).
+Use `bool` query instead, which supports `filter` clauses too.
+
+## Limit Query removed
+
+The `limit` query has been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_search_changes.html#_deprecated_queries_removed).
+Use the `terminate_after` parameter instead.
+
+# Template Query removed
+
+The `template` query has been [deprecated](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/query-dsl-template-query.html). You should use
+Search Templates instead.
+
+We remove it from Elastic 5.0 as the 5.0 update is already a good opportunity
+to get rid of old stuff.
+
+## `_timestamp` and `_ttl` removed
+
+Both of these fields were deprecated and are now [removed](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_mapping_changes.html#_literal__timestamp_literal_and_literal__ttl_literal).
+
+## Search template Put/Delete API returns `acknowledged` only
+
+The response type for Put/Delete search templates has changed.
+It only returns a single `acknowledged` flag now.
+
+## Fields has been renamed to Stored Fields
+
+The `fields` parameter has been renamed to `stored_fields`.
+See [here](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/breaking_50_search_changes.html#_literal_fields_literal_parameter).
+
+## Fielddatafields has been renamed to Docvaluefields
+
+The `fielddata_fields` parameter [has been renamed](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/breaking_50_search_changes.html#_literal_fielddata_fields_literal_parameter)
+to `docvalue_fields`.
+
+## Type exists endpoint changed
+
+The endpoint for checking whether a type exists has been changed from
+`HEAD {index}/{type}` to `HEAD {index}/_mapping/{type}`.
+See [here](https://www.elastic.co/guide/en/elasticsearch/reference/5.0/breaking_50_rest_api_changes.html#_literal_head_index_type_literal_replaced_with_literal_head_index__mapping_type_literal).
+
+## Refresh parameter changed
+
+The `?refresh` parameter previously could be a boolean value. It indicated
+whether changes made by a request (e.g. by the Bulk API) should be immediately
+visible in search, or not. Using `refresh=true` had the positive effect of
+immediately seeing the changes when searching; the negative effect is that
+it is a rather big performance hit.
+
+With 5.0, you now have the choice between these 3 values.
+
+* `"true"` - Refresh immediately
+* `"false"` - Do not refresh (the default value)
+* `"wait_for"` - Wait until ES made the document visible in search
+
+See [?refresh](https://www.elastic.co/guide/en/elasticsearch/reference/master/docs-refresh.html) in the documentation.
+
+Notice that `true` and `false` (the boolean values) are no longer available
+now in Elastic. You must use a string instead, with one of the above values.
+
+## ReindexerService removed
+
+The `ReindexerService` was a custom solution that was started in the ES 1.x era
+to automate reindexing data, from one index to another or even between clusters.
+
+ES 2.3 introduced its own [Reindex API](https://www.elastic.co/guide/en/elasticsearch/reference/master/docs-reindex.html)
+so we're going to remove our custom solution and ask you to use the native reindexer.
+
+The `ReindexService` is available via `client.Reindex()` (which used to point
+to the custom reindexer).
+
+## Delete By Query back in core
+
+The [Delete By Query API](https://www.elastic.co/guide/en/elasticsearch/reference/master/docs-delete-by-query.html)
+was moved into a plugin in 2.0. Now its back in core with a complete rewrite based on the Bulk API.
+
+It has it's own endpoint at `/_delete_by_query`.
+
+Delete By Query, Reindex, and Update By Query are very similar under the hood.
+
+## Reindex, Delete By Query, and Update By Query response changed
+
+The response from the above APIs changed a bit. E.g. the `retries` value
+used to be an `int64` and returns separate values for `bulk` and `search` now:
+
+```
+// Old
+{
+    ...
+    "retries": 123,
+    ...
+}
+```
+
+```
+// New
+{
+    ...
+    "retries": {
+        "bulk": 123,
+        "search": 0
+    },
+    ...
+}
+```
+
+## ScanService removed
+
+The `ScanService` is removed. Use the (new) `ScrollService` instead.
+
+## New ScrollService
+
+There was confusion around `ScanService` and `ScrollService` doing basically
+the same. One was returning slices and didn't support all query details, the
+other returned one document after another and wasn't safe for concurrent use.
+So we merged the two and merged it into a new `ScrollService` that
+removes all the problems with the older services.
+
+In other words:
+If you used `ScanService`, switch to `ScrollService`.
+If you used the old `ScrollService`, you might need to fix some things but
+overall it should just work.
+
+Changes:
+- We replaced `elastic.EOS` with `io.EOF` to indicate the "end of scroll".
+
+TODO Not implemented yet
+
+## Suggesters
+
+They have been [completely rewritten in ES 5.0](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_suggester.html).
+
+Some changes:
+- Suggesters no longer have an [output](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_suggester.html#_simpler_completion_indexing).
+
+TODO Fix all structural changes in suggesters
+
+## Percolator
+
+Percolator has [changed considerably](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/breaking_50_percolator.html).
+
+Elastic 5.0 adds the new
+[Percolator Query](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/query-dsl-percolate-query.html)
+which can be used in combination with the new
+[Percolator type](https://www.elastic.co/guide/en/elasticsearch/reference/5.x/percolator.html).
+
+The Percolate service is removed from Elastic 5.0.
+
+## Remove Consistency, add WaitForActiveShards
+
+The `consistency` parameter has been removed in a lot of places, e.g. the Bulk,
+Index, Delete, Delete-by-Query, Reindex, Update, and Update-by-Query API.
+
+It has been replaced by a somewhat similar `wait_for_active_shards` parameter.
+See https://github.com/elastic/elasticsearch/pull/19454.

+# How to contribute
+
+Elastic is an open-source project and we are looking forward to each
+contribution.
+
+Notice that while the [official Elasticsearch documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/index.html) is rather good, it is a high-level
+overview of the features of Elasticsearch. However, Elastic tries to resemble
+the Java API of Elasticsearch which you can find [on GitHub](https://github.com/elastic/elasticsearch).
+
+This explains why you might think that some options are strange or missing
+in Elastic, while often they're just different. Please check the Java API first.
+
+Having said that: Elasticsearch is moving fast and it might be very likely
+that we missed some features or changes. Feel free to change that.
+
+## Your Pull Request
+
+To make it easy to review and understand your changes, please keep the
+following things in mind before submitting your pull request:
+
+* You compared the existing implementation with the Java API, did you?
+* Please work on the latest possible state of `olivere/elastic`.
+  Use `release-branch.v2` for targeting Elasticsearch 1.x and
+  `release-branch.v3` for targeting 2.x.
+* Create a branch dedicated to your change.
+* If possible, write a test case which confirms your change.
+* Make sure your changes and your tests work with all recent versions of
+  Elasticsearch. We currently support Elasticsearch 1.7.x in the
+  release-branch.v2 and Elasticsearch 2.x in the release-branch.v3.
+* Test your changes before creating a pull request (`go test ./...`).
+* Don't mix several features or bug fixes in one pull request.
+* Create a meaningful commit message.
+* Explain your change, e.g. provide a link to the issue you are fixing and
+  probably a link to the Elasticsearch documentation and/or source code.
+* Format your source with `go fmt`.
+

+
+**Example:**
+
+You have installed Elasticsearch 7.0.0 and want to use Elastic.
+As listed above, you should use Elastic 7.0 (code is in `release-branch.v7`).
+
+To use the required version of Elastic in your application, you
+should use [Go modules](https://github.com/golang/go/wiki/Modules)
+to manage dependencies. Make sure to use a version such as `7.0.0` or later.
+
+To use Elastic, import:
+
+```go
+import "github.com/olivere/elastic/v7"
+```
+
+### Elastic 7.0
+
+Elastic 7.0 targets Elasticsearch 7.x which [was released on April 10th 2019](https://www.elastic.co/guide/en/elasticsearch/reference/7.0/release-notes-7.0.0.html).
+
+As always with major version, there are a lot of [breaking changes](https://www.elastic.co/guide/en/elasticsearch/reference/7.0/release-notes-7.0.0.html#breaking-7.0.0).
+We will use this as an opportunity to [clean up and refactor Elastic](https://github.com/olivere/elastic/blob/release-branch.v7/CHANGELOG-7.0.md),
+as we already did in earlier (major) releases.
+
+### Elastic 6.0
+
+Elastic 6.0 targets Elasticsearch 6.x which was [released on 14th November 2017](https://www.elastic.co/blog/elasticsearch-6-0-0-released).
+
+Notice that there are a lot of [breaking changes in Elasticsearch 6.0](https://www.elastic.co/guide/en/elasticsearch/reference/6.7/breaking-changes-6.0.html)
+and we used this as an opportunity to [clean up and refactor Elastic](https://github.com/olivere/elastic/blob/release-branch.v6/CHANGELOG-6.0.md)
+as we did in the transition from earlier versions of Elastic.
+
+### Elastic 5.0
+
+Elastic 5.0 targets Elasticsearch 5.0.0 and later. Elasticsearch 5.0.0 was
+[released on 26th October 2016](https://www.elastic.co/blog/elasticsearch-5-0-0-released).
+
+Notice that there are will be a lot of [breaking changes in Elasticsearch 5.0](https://www.elastic.co/guide/en/elasticsearch/reference/5.0/breaking-changes-5.0.html)
+and we used this as an opportunity to [clean up and refactor Elastic](https://github.com/olivere/elastic/blob/release-branch.v5/CHANGELOG-5.0.md)
+as we did in the transition from Elastic 2.0 (for Elasticsearch 1.x) to Elastic 3.0 (for Elasticsearch 2.x).
+
+Furthermore, the jump in version numbers will give us a chance to be in sync with the Elastic Stack.
+
+### Elastic 3.0
+
+Elastic 3.0 targets Elasticsearch 2.x and is published via [`gopkg.in/olivere/elastic.v3`](https://gopkg.in/olivere/elastic.v3).
+
+Elastic 3.0 will only get critical bug fixes. You should update to a recent version.
+
+### Elastic 2.0
+
+Elastic 2.0 targets Elasticsearch 1.x and is published via [`gopkg.in/olivere/elastic.v2`](https://gopkg.in/olivere/elastic.v2).
+
+Elastic 2.0 will only get critical bug fixes. You should update to a recent version.
+
+### Elastic 1.0
+
+Elastic 1.0 is deprecated. You should really update Elasticsearch and Elastic
+to a recent version.
+
+However, if you cannot update for some reason, don't worry. Version 1.0 is
+still available. All you need to do is go-get it and change your import path
+as described above.
+
+
+## Status
+
+We use Elastic in production since 2012. Elastic is stable but the API changes
+now and then. We strive for API compatibility.
+However, Elasticsearch sometimes introduces [breaking changes](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking-changes.html)
+and we sometimes have to adapt.
+
+Having said that, there have been no big API changes that required you
+to rewrite your application big time. More often than not it's renaming APIs
+and adding/removing features so that Elastic is in sync with Elasticsearch.
+
+Elastic has been used in production starting with Elasticsearch 0.90 up to recent 7.x
+versions. Furthermore, we use [Travis CI](https://travis-ci.org/)
+to test Elastic with the most recent versions of Elasticsearch and Go.
+See the [.travis.yml](https://github.com/olivere/elastic/blob/master/.travis.yml)
+file for the exact matrix and [Travis](https://travis-ci.org/olivere/elastic)
+for the results.
+
+Elasticsearch has quite a few features. Most of them are implemented
+by Elastic. I add features and APIs as required. It's straightforward
+to implement missing pieces. I'm accepting pull requests :-)
+
+Having said that, I hope you find the project useful.
+
+
+## Getting Started
+
+The first thing you do is to create a [Client](https://github.com/olivere/elastic/blob/master/client.go).
+The client connects to Elasticsearch on `http://127.0.0.1:9200` by default.
+
+You typically create one client for your app. Here's a complete example of
+creating a client, creating an index, adding a document, executing a search etc.
+
+An example is available [here](https://olivere.github.io/elastic/).
+
+Here's a [link to a complete working example for v6](https://gist.github.com/olivere/e4a376b4783c0914e44ea4f745ce2ebf).
+
+Here are a few tips on how to get used to Elastic:
+
+1. Head over to the [Wiki](https://github.com/olivere/elastic/wiki) for detailed information and
+   topics like e.g. [how to add a middleware](https://github.com/olivere/elastic/wiki/HttpTransport)
+   or how to [connect to AWS](https://github.com/olivere/elastic/wiki/Using-with-AWS-Elasticsearch-Service).
+2. If you are unsure how to implement something, read the tests (all `_test.go` files).
+   They not only serve as a guard against changes, but also as a reference.
+3. The [recipes](https://github.com/olivere/elastic/tree/release-branch.v6/recipes)
+   contains small examples on how to implement something, e.g. bulk indexing, scrolling etc.

+The first thing you do is to create a Client. If you have Elasticsearch
+installed and running with its default settings
+(i.e. available at http://127.0.0.1:9200), all you need to do is:
+
+	client, err := elastic.NewClient()
+	if err != nil {
+		// Handle error
+	}
+
+If your Elasticsearch server is running on a different IP and/or port,
+just provide a URL to NewClient:
+
+  // Create a client and connect to http://192.168.2.10:9201
+  client, err := elastic.NewClient(elastic.SetURL("http://192.168.2.10:9201"))
+  if err != nil {
+    // Handle error
+  }
+
+You can pass many more configuration parameters to NewClient. Review the
+documentation of NewClient for more information.
+
+If no Elasticsearch server is available, services will fail when creating
+a new request and will return ErrNoClient.
+
+A Client provides services. The services usually come with a variety of
+methods to prepare the query and a Do function to execute it against the
+Elasticsearch REST interface and return a response. Here is an example
+of the IndexExists service that checks if a given index already exists.
+
+	exists, err := client.IndexExists("twitter").Do(context.Background())
+	if err != nil {
+		// Handle error
+	}
+	if !exists {
+		// Index does not exist yet.
+	}
+
+Look up the documentation for Client to get an idea of the services provided
+and what kinds of responses you get when executing the Do function of a service.
+Also see the wiki on Github for more details.
