Did you know there is (next to the well known Nominatim) a new open source geocoder ("Name and Adress Search") built for OpenStreetMap data?
(found this link via http://wiki.openstreetmap.org/wiki/Search_engines )
The demonstration website on komoot.de is quite impressive! I had a wish for such a feature (incremental and instant search) for years!
Anyone who finds wrong results or missing features / data?
