Hi,
After several false starts the goecoding tool I've been working on seems to have succeeded in indexing the full planet file and it is now available for people to experiment with here:
Cool thing!
Below you'll find some things I found. Maybe they are fixable, maybe not.
gustav-heinemann-straße gau-odernheim -> ok gustav-heinemann-str gau-odernheim -> nothing gustav-heinemann-str. gau-odernheim -> nothing gustav-heinemann-straße 55239 -> nothing 55239 -> nothing
the node has openGeoDB:postal_codes=55239 set: http://www.openstreetmap.org/browse/node/139549564
Gustav-Heinemann Straße, Gau-Köngernheim, Gau-Odernheim, Germany
gustav-heinemann-straße gau-odernheim -> states "Gustav-Heinemann Straße, Gau-Köngernheim, Gau-Odernheim, Germany"
although this street is just in Gau-Odernheim, as stated by the is_in tag of the node named above: is_in = Alzey-Worms,Rheinhessen-Pfalz,Rheinland-Pfalz,Bundesrepublik Deutschland,Europe
Gau-Köngernheim is tagged as suburb where it should maybe better be tagged as municipality or district (?) it is administrational a part of the village Gau-Odernheim but not spatially..
Thank you for that cool-tool! Peter
