ElasticsearchAutocomplete

Simple autocomplete for rails models using awesome Elasticsearch.

Look at ElasticsearchAutocomplete example app

Add this line to your application's Gemfile:

gem 'elasticsearch_autocomplete'

And then execute:

$ bundle

Or install it yourself as:

$ gem install elasticsearch_autocomplete

Specify attributes for autocompletion. By default, this is name attribute:

class User < ActiveRecord::Base
  ac_field :full_name
end

Don't forget to rebuild elasticsearch index:

    $ rake environment tire:import CLASS='User' FORCE=true

To find suggestions call ac_search method on your model. It return Tire::Results::Collection instance:

User.ac_search('Alex').map(&:full_name)
=> ['Alex First', 'Alexandr Second']

You can specify fields for suggestions search:

class User < ActiveRecord::Base
  ac_field :full_name, search_fields: [:full_name, :email]
end

For search on localized fields such as name_en, name_ru:

class Product < ActiveRecord::Base
  ac_field :name, localized: true
end

If you want to define settings and mapping for elasticsearch index yourselves:

class Product < ActiveRecord::Base
  ac_field :name, skip_settings: true
end
