A Rails Controller uses Tire to interface with ElasticSearch.

search_controller.rb

class SearchController < ApplicationController
  def ajax
    q = request.GET[:q]
    @s = Tire.search(sha1 current_user.email) do
      query do
        string q
      end
      highlight :text, :options => { :tag => '<strong class="highlight">' }
    end
    puts @s.to_curl
    render :json => @s.results, :layout => false
  end
end
