Filtering by multiple filters does not always work

[autumnus]

The search API says:

Note: not all tags on link in the title are supported. Please see nominatim source for an accurate list. If one or many query parameters named osm_tag are present, photon will attempt to filter results by those tags. In general, here is the expected format (syntax) for the value of osm_tag request parameters.

In general that works:
http://photon.komoot.de/api/?q=kyoto&lang=de&osm_tag=place:city&limit=100
http://photon.komoot.de/api/?q=kyoto&lang=de&osm_tag=place:town&limit=100
http://photon.komoot.de/api/?q=kyoto&lang=de&osm_tag=place:village&limit=100

But combining does not always work:
http://photon.komoot.de/api/?q=kyoto&lang=de&osm_tag=place:city&osm_tag=place:town&limit=100 (works)
http://photon.komoot.de/api/?q=kyoto&lang=de&osm_tag=place:city&osm_tag=place:village&limit=100 (does NOT work)

(That way I tried to work around my issue #322)

Best regards,
Autumnus

Could you please describe why you think that the last query does not work? It returns results with place:city and place:village. What behavior do you expect?
