Spatial filtering. Supported are bbox, proximity, tile, corridor and all (full layer).
The format is &in=all or
&in=bbox:{west longitude},{south latitude},{east longitude},{north latitude} or
&in=proximity:latitude,longitude;r={radius} or
&in=tile:{comma separated list of tile ids. The number of tile ids must match with the number of layers.} or
&in=corridor:{comma separated WGS84 degree coordinates of corridor, for example:latitude 1,longitude 1,latitude 2,longitude 2 / encoded polyline string from Routing v8 response/ routeHandle string from Routing v8 response};r={radius}[;type=geoCoordinate(gc)/encodedPolyline(ep)/routeHandle(rh) }.
When using routeHandle for corridor search an access token or apikey used for the router v8 service should be specified as Authorization header, else request will fail.
