False positive on admin border

[wolfbert]

This is the first false positive I've encountered and I don't consider it severe, just for your information. Probably unavoidable.

https://nominatim.org/qa/#map=18.86/48.13/15.13&layer=addr_street_wrong_name (zoom out, it's in the lower right corner)

Note that the addresses in question are linked to the street on the wrong side of the admin border.

In the past month I worked with the same data layer regularly. With the 1000s of warnings in Germany alone there's always something to fix (in OSM data). I do see false positives, too, and currently ignore them.

With the postcode layer I fixed central Europe over several weeks and many false positives. For example a mountain in Germany hut can only be reached from Austria so it has an Austrian postcode. Or a building is exactly through a country border.

Interesting corner case. Definitely worth tracking as a bug in Nominatim. I'll move it over. No promises though that it will get fixed any time soon.
