Install the Rubygem for the latest {es} version by using the following command:
gem install elasticsearchOr 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 7.0.0Or you can add a specific version of {es} to your Gemfile:
gem 'elasticsearch', '~> 7.0'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.
