We are currently in the process of adopting Graphhopper for a couple of tasks, one of them beeing lookup of postal codes to filter objects based on their location.
I am currently evaluating the usage of Graphhoppers Geocode API, am however struggling with the generic nature of the APIs query parameter. When I query a postal code, sometimes it will show a correct hit, most times though it will consider e.g. a Street in the U.S. as a more accurate result.
Now according to the documentation the API supports different providers, one of them being nominatim, which according to their documentation supports structured queries. Is it possible to pass those through from the Graphhopper to the nominatim-API?
