[Geocoding] City information missing/wrong

Hi,

I'm trying to use the Nominatim geocoder and to evaluate the quality of a given result (by comparing the data returned with the data asked for), but here I found a problem...

"Keilberg" is a suburb of "Regensburg". When querying it, for example...

q=rotdornweg, regensburg

..I'll get something like this...

                               "address" : {
                                               "road" : "Rotdornweg",
                                               "suburb" : "Keilberg",
                                               "county" : "Regensburg",
                                               "state_district" : "Regierungsbezirk Oberpfalz",
                                               "state" : "Free State of Bavaria",
                                               "country" : "Germany",
                                               "country_code" : "de"
                               }

The information, that the city is called "Regensburg" is somehow totally lost. Is there any chance to get the information about the city in the result? There IS a marker for Keilberg in the osm map data with "isIn" "Regensburg,Regensburg,Oberpfalz,Bayern,Bundesrepublik Deutschland".

Another example would be...

q=Gartenweg, Regensburg

...which results in...

                                               "road" : "Gartenweg",
                                               "suburb" : "Irl",
                                               "village" : "Harting",
                                               "county" : "Regensburg",
                                               "state_district" : "Regierungsbezirk Oberpfalz",
                                               "state" : "Free State of Bavaria",
                                               "postcode" : "93055",
                                               "country" : "Germany",
                                               "country_code" : "de",
                                               "continent" : "European Union"

Is this just a data error? Harting is not a village, but a suburb.

Regards,

Flo
