This demo shows how to use a boundary.circle.lat and boundary.circle.lon spatially limit the results
when performing an autocomplete search.
Results will be limited to features that fall within a specified radius distance.
boundary.circle.lat
and
boundary.circle.lon
define the center point of the search area, while
boundary.circle.radius
sets the radius (in km).
Unlike a focus point (which boosts nearby matches but can still return distant results),
a boundary circle will exclude all results that fall outside the specified radius.
For example, searching for “McDonalds” with a boundary circle centered in
-22.919, -43.225 (Rio de Janeiro) and a radius of 750 meters (0.75 km) will only return McDonalds locations
within that 750 m area. Locations outside the circle will not be included in the results.
