Add access format support for Elasticsearch notification target (#4006)

This change adds `access` format support for notifications to a
Elasticsearch server, and it refactors `namespace` format support.

In the case of `access` format, for each event in Minio, a JSON
document is inserted into Elasticsearch with its timestamp set to the
event's timestamp, and with the ID generated automatically by
elasticsearch. No events are modified or deleted in this mode.

In the case of `namespace` format, for each event in Minio, a JSON
document is keyed together by the bucket and object name is updated in
Elasticsearch. In the case of an object being created or over-written
in Minio, a new document or an existing document is inserted into the
Elasticsearch index. If an object is deleted in Minio, the
corresponding document is deleted from the Elasticsearch index.

Additionally, this change upgrades Elasticsearch support to the 5.x
series. This is a breaking change, and users of previous elasticsearch
versions should upgrade.

Also updates documentation on Elasticsearch notification target usage
and has a link to an elasticsearch upgrade guide.

This is the last patch that finally resolves #3928.

# 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.

# 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 implemenation 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 ./...`).

# Elastic
Elastic is an [Elasticsearch](http://www.elasticsearch.org/) client for the
[Go](http://www.golang.org/) programming language.
[![Build Status](https://travis-ci.org/olivere/elastic.svg?branch=release-branch.v5)](https://travis-ci.org/olivere/elastic)
[![Godoc](http://img.shields.io/badge/godoc-reference-blue.svg?style=flat)](http://godoc.org/gopkg.in/olivere/elastic.v5)
[![license](http://img.shields.io/badge/license-MIT-red.svg?style=flat)](https://raw.githubusercontent.com/olivere/elastic/master/LICENSE)
See the [wiki](https://github.com/olivere/elastic/wiki) for additional information about Elastic.
## Releases
**The release branches (e.g. [`release-branch.v5`](https://github.com/olivere/elastic/tree/release-branch.v5))
are actively being worked on and can break at any time.
If you want to use stable versions of Elastic, please use the packages released via [gopkg.in](https://gopkg.in).**
Here's the version matrix:
Elasticsearch version | Elastic version -| Package URL
----------------------|------------------|------------
5.x | 5.0 | [`gopkg.in/olivere/elastic.v5`](https://gopkg.in/olivere/elastic.v5) ([source](https://github.com/olivere/elastic/tree/release-branch.v5) [doc](http://godoc.org/gopkg.in/olivere/elastic.v5))
2.x | 3.0 | [`gopkg.in/olivere/elastic.v3`](https://gopkg.in/olivere/elastic.v3) ([source](https://github.com/olivere/elastic/tree/release-branch.v3) [doc](http://godoc.org/gopkg.in/olivere/elastic.v3))
1.x | 2.0 | [`gopkg.in/olivere/elastic.v2`](https://gopkg.in/olivere/elastic.v2) ([source](https://github.com/olivere/elastic/tree/release-branch.v2) [doc](http://godoc.org/gopkg.in/olivere/elastic.v2))
0.9-1.3 | 1.0 | [`gopkg.in/olivere/elastic.v1`](https://gopkg.in/olivere/elastic.v1) ([source](https://github.com/olivere/elastic/tree/release-branch.v1) [doc](http://godoc.org/gopkg.in/olivere/elastic.v1))
**Example:**
You have installed Elasticsearch 5.0.0 and want to use Elastic.
As listed above, you should use Elastic 5.0.
So you first install the stable release of Elastic 5.0 from gopkg.in.
```sh
$ go get gopkg.in/olivere/elastic.v5
```
You then import it with this import path:
```go
import elastic "gopkg.in/olivere/elastic.v5"
```
### 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 with the following Elasticsearch versions:
0.90, 1.0-1.7, and 2.0-2.4.1. 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.
```go
// Create a context
ctx := context.Background()
// Create a client
client, err := elastic.NewClient()
if err != nil {
// Handle error
panic(err)
}
// Create an index
_, err = client.CreateIndex("twitter").Do(ctx)
if err != nil {
// Handle error
panic(err)
}
// Add a document to the index
tweet := Tweet{User: "olivere", Message: "Take Five"}
_, err = client.Index().
Index("twitter").
Type("tweet").
Id("1").
BodyJson(tweet).
Refresh("true").
Do(ctx)
if err != nil {
// Handle error
panic(err)
}
// Search with a term query
termQuery := elastic.NewTermQuery("user", "olivere")
searchResult, err := client.Search().
Index("twitter"). // search in index "twitter"
Query(termQuery). // specify the query
Sort("user", true). // sort by "user" field, ascending
From(0).Size(10). // take documents 0-9
Pretty(true). // pretty print request and response JSON
Do(ctx) // execute
if err != nil {
// Handle error
panic(err)
}
// searchResult is of type SearchResult and returns hits, suggestions,
// and all kinds of other information from Elasticsearch.
fmt.Printf("Query took %d milliseconds\n", searchResult.TookInMillis)
// Each is a convenience function that iterates over hits in a search result.
// It makes sure you don't need to check for nil values in the response.
// However, it ignores errors in serialization. If you want full control
// over iterating the hits, see below.
var ttyp Tweet
for _, item := range searchResult.Each(reflect.TypeOf(ttyp)) {
if t, ok := item.(Tweet); ok {
fmt.Printf("Tweet by %s: %s\n", t.User, t.Message)
}
}
// TotalHits is another convenience function that works even when something goes wrong.
fmt.Printf("Found a total of %d tweets\n", searchResult.TotalHits())
// Here's how you iterate through results with full control over each step.
if searchResult.Hits.TotalHits > 0 {
fmt.Printf("Found a total of %d tweets\n", searchResult.Hits.TotalHits)
// Iterate through results
for _, hit := range searchResult.Hits.Hits {
// hit.Index contains the name of the index
// Deserialize hit.Source into a Tweet (could also be just a map[string]interface{}).
var t Tweet
err := json.Unmarshal(*hit.Source, &t)
if err != nil {
// Deserialization failed
}
// Work with tweet
fmt.Printf("Tweet by %s: %s\n", t.User, t.Message)
}
} else {
// No hits
fmt.Print("Found no tweets\n")
}
// Delete the index again
_, err = client.DeleteIndex("twitter").Do(ctx)
if err != nil {
// Handle error
panic(err)
}
```
Here's a [link to a complete working example](https://gist.github.com/olivere/114347ff9d9cfdca7bdc0ecea8b82263).

/*
Package elastic provides an interface to the Elasticsearch server
(https://www.elastic.co/products/elasticsearch).
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.
