A filter of one or more address types, separated by a pipe (|). If the parameter contains multiple address types, the API returns all addresses that match any of the types. A note about processing: The result_type parameter does not restrict the search to the specified address type(s). Rather, the result_type acts as a post-search filter: the API fetches all results for the specified latlng, then discards those results that do not match the specified address type(s).
The following values are supported:
administrative_area_level_1 .. administrative_area_level_5
