Elasticsearch
This repository contains ActiveModel, ActiveRecord and Ruby on Rails integrations for Elasticsearch:
- ActiveModel integration with adapters for ActiveRecord and Mongoid
- Enumerable-based wrapper for search results
- ActiveRecord::Relation-based wrapper for returning search results as records
- Model methods such as
search
,mapping
, etc - Pagination support
- Rails application templates
NOTE: This is a pre-release version: feedback welcome via Github issues, e-mail or IRC. Many more features, such as automatic hooking into Rails' notifications, Elasticsearch persistence for models, etc. are planned or being worked on.

method, pagination, etc -
elasticsearch-rails
, which contains features for Ruby on Rails applications

require 'elasticsearch/model'
class Article < ActiveRecord::Base
include Elasticsearch::Model
include Elasticsearch::Model::Callbacks
end
Article.import
@articles = Article.search('foobar').records
You can generate a fully working Ruby on Rails application with a single command:
