# go-elasticsearch The official Go client for [Elasticsearch](https://www.elastic.co/products/elasticsearch). [](https://pkg.go.dev/github.com/elastic/go-elasticsearch/v9) [](https://goreportcard.com/report/github.com/elastic/go-elasticsearch) [](https://github.com/elastic/go-elasticsearch/actions/workflows/build.yml?query=branch%3Amain) [](https://github.com/elastic/go-elasticsearch/actions/workflows/test-unit.yml?query=branch%3Amain) [](https://github.com/elastic/go-elasticsearch/actions/workflows/test-integration.yml?query=branch%3Amain) [](https://github.com/elastic/go-elasticsearch/actions/workflows/test-api.yml?query=branch%3Amain) [](https://github.com/elastic/go-elasticsearch/actions/workflows/lint.yml) ## Documentation Find the full reference documentation at [elastic.co](https://www.elastic.co/docs/reference/elasticsearch/clients/go): - [Getting started](https://www.elastic.co/docs/reference/elasticsearch/clients/go/getting-started) - [Configuration](https://www.elastic.co/docs/reference/elasticsearch/clients/go/configuration) - [Using the API](https://www.elastic.co/docs/reference/elasticsearch/clients/go/using-the-api) (low-level and typed) - [Typed API](https://www.elastic.co/docs/reference/elasticsearch/clients/go/typed-api) and [esdsl builders](https://www.elastic.co/docs/reference/elasticsearch/clients/go/typed-api/esdsl) - [Advanced topics](https://www.elastic.co/docs/reference/elasticsearch/clients/go/advanced) (interceptors, observability) The Go package reference lives on [pkg.go.dev](https://pkg.go.dev/github.com/elastic/go-elasticsearch/v9). ## Compatibility ### Go Starting from version `8.12.0`, this library follows the Go language's [release policy](https://go.dev/doc/devel/release#policy). Each major Go release is supported until there are two newer major releases. For example, Go 1.5 was supported until the Go 1.7 release, and Go 1.6 was supported until the Go 1.8 release. ### Elasticsearch When using Go modules, include the version in the import path, and specify either an explicit version or a branch: require github.com/elastic/go-elasticsearch/v9 v9.x.x require github.com/elastic/go-elasticsearch/v8 v8.x.x It's possible to use multiple versions of the client in a single project: // go.mod github.com/elastic/go-elasticsearch/v8 v8.18.0 github.com/elastic/go-elasticsearch/v9 v9.0.0 // main.go import ( elasticsearch8 "github.com/elastic/go-elasticsearch/v8" elasticsearch9 "github.com/elastic/go-elasticsearch/v9" ) // ... es8, _ := elasticsearch8.New() es9, _ := elasticsearch9.New() The `main` branch of the client is compatible with the current `master` branch of Elasticsearch. ## Installation Refer to the [Installation](https://www.elastic.co/docs/reference/elasticsearch/clients/go/installation) page of the documentation. ## Connecting Refer to the [Connecting](https://www.elastic.co/docs/reference/elasticsearch/clients/go/connecting) page of the documentation. ## Operations - [Creating an index](https://www.elastic.co/docs/reference/elasticsearch/clients/go/using-the-api/crud-operations) - [Indexing documents](https://www.elastic.co/docs/reference/elasticsearch/clients/go/using-the-api/crud-operations) - [Getting documents](https://www.elastic.co/docs/reference/elasticsearch/clients/go/using-the-api/crud-operations) - [Searching documents](https://www.elastic.co/docs/reference/elasticsearch/clients/go/using-the-api/searching) - [Updating documents](https://www.elastic.co/docs/reference/elasticsearch/clients/go/using-the-api/crud-operations) - [Deleting documents](https://www.elastic.co/docs/reference/elasticsearch/clients/go/using-the-api/crud-operations) - [Deleting an index](https://www.elastic.co/docs/reference/elasticsearch/clients/go/using-the-api/crud-operations) ## Helpers The `esutil` package provides convenience helpers for working with the client. At the moment, it provides the `esutil.JSONReader()` and the [`esutil.BulkIndexer`](https://www.elastic.co/docs/reference/elasticsearch/clients/go/using-the-api/bulk-indexing) helpers. ## Examples The **[`_examples`](./_examples)** folder contains a number of recipes and comprehensive examples to get you started with the client, including configuration and customization of the client, using a custom certificate authority (CA) for security (TLS), mocking the transport for unit tests, embedding the client in a custom type, building queries, performing requests individually and in bulk, and parsing the responses. ## License This software is licensed under the [Apache 2 license](./LICENSE).
