Installation [ruby-install]

Install the Rubygem for the latest {{es}} version by using the following command:

gem install elasticsearch

Or add the elasticsearch Ruby gem to your Gemfile:

gem 'elasticsearch'

You can install the Ruby gem for a specific {{es}} version by using the following command:

gem install elasticsearch -v 7.0.0

Or you can add a specific version of {{es}} to your Gemfile:

gem 'elasticsearch', '~> 7.0'

{{es}} and Ruby version compatibility [_es_and_ruby_version_compatibility]

The {{es}} client is compatible with currently maintained Ruby versions. We follow Ruby’s own maintenance policy and officially support all currently maintained versions per Ruby Maintenance Branches.

Language clients are forward compatible; meaning that clients support communicating with greater or equal minor versions of {{es}} without breaking. It does not mean that the client automatically supports new features of newer {{es}} versions; it is only possible after a release of a new client version. For example, a 8.12 client version won’t automatically support the new features of the 8.13 version of {{es}}, the 8.13 client version is required for that. {{es}} language clients are only backwards compatible with default distributions and without guarantees made.

Gem Version {{es}} Version Supported
7.x → 7.x 7.17
8.x → 8.x 8.x
main → main
