ActiveModel / ActiveRecordedit

The elasticsearch-model Rubygem provides integration with Ruby domain objects ("models"), commonly found for example, in Ruby on Rails applications.

It uses the elasticsearch Rubygem as the client communicating with the Elasticsearch cluster.


  • ActiveModel integration with adapters for ActiveRecord and Mongoid
  • Enumerable-based wrapper for search results
  • ActiveRecord::Relation-based wrapper for returning search results as records
  • Convenience model methods such as search, mapping, import, etc
  • Support for Kaminari and WillPaginate pagination
  • Extension implemented via proxy object to shield model namespace from collisions
  • Convenience methods for (re)creating the index, setting up mappings, indexing documents, …​


Add the library to your Gemfile:

gem 'elasticsearch-rails'

Include the extension module in your model class:

class Article < ActiveRecord::Base
  include Elasticsearch::Model

Import some data and perform a search:


response = 'fox dog'
# => 3

It is possible to either return results as model instances, or decorated documents from Elasticsearch, with the records and results methods, respectively:

# Article Load (0.4ms)  SELECT "articles".* FROM "articles"  WHERE ...
=> #<Article id: 3, title: "Foo " ...>

# => 0.02250402

# => "Quick brown fox"
