gistfile1.rb

 def index
  Thread.abort_on_exception = true
  
  thr_one = Thread.new do
    @list_one = ModelOne.find_model_ones_in_elasticsearch(params[:page])
  end

  thr_two = Thread.new do
    @list_two = ModelTwo.find_model_twos_in_elasticsearch(params[:page])
  end

    # Pause the main thread and allow our threads to execute
  thr_one.join
  thr_two.join

  # Ensure we clean up our threads after processing is finished
  thr_one.exit
  thr_two.exit

  render json: {ones: @list_one, twos: @list_two}, root: false, serializer: SomeSerializer
end
