Something like:

Tire.search 'venues' do
  query do
    filtered do
      query { all }
      filter :geo_polygon, location: { points: [
                                        {lat: 40, lon -70},
                                        {lat: 30, lon -80},
                                        {lat: 20, lon -90}
                                       ]
                                      }
    end
  end
end
