# ActiveModel / ActiveRecord
The `elasticsearch-model` [Rubygem](http://rubygems.org/gems/elasticsearch-model) 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.

## Features

- 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, …


## Usage

Add the library to your Gemfile:
```ruby
gem 'elasticsearch-rails'
```

Include the extension module in your model class:
```ruby
class Article < ActiveRecord::Base
  include Elasticsearch::Model
end
```

Import some data and perform a search:
```ruby
Article.import

response = Article.search 'fox dog'
response.took
# => 3
```

It is possible to either return results as model instances, or decorated documents from Elasticsearch, with the `records` and `results` methods, respectively:
```ruby
response.records.first
# Article Load (0.4ms)  SELECT "articles".* FROM "articles"  WHERE ...
=> #<Article id: 3, title: "Foo " ...>

response.results.first._score
# => 0.02250402

response.results.first._source.title
# => "Quick brown fox"
```
