   Prefer results in a specified area, by specifying either a radius plus lat/lng, or two lat/lng pairs representing the points of a rectangle. If this parameter is not specified, the API uses IP address biasing by default.
   - IP bias: Instructs the API to use IP address biasing. Pass the string `ipbias` (this option has no additional parameters).
-  - Point: A single lat/lng coordinate. Use the following format: `point:lat,lng`.
   - Circular: A string specifying radius in meters, plus lat/lng in decimal degrees. Use the following format: `circle:radius@lat,lng`.
   - Rectangular: A string specifying two lat/lng pairs in decimal degrees, representing the south/west and north/east points of a rectangle. Use the following format:`rectangle:south,west|north,east`. Note that east/west values are wrapped to the range -180, 180, and north/south values are clamped to the range -90, 90.
