Thanks to Thorsten for the valuable hint ... This quick-and-dirty solution solves the problem: An alternative solution could be this ("admin_level 7" will completely be ignored): In germany "admin_level 7" is used for special or artificial administration regions. Mostly they are called "Ämter", "Verbandsgemeinden" or "Verwaltungsgemeinschaften". People typically don't use these objects as starting point for an address search. But this solution needs some more quality assurance ... I want to verify the "address index" against an official german register (called AGS "Amtlicher Gemeindeschlüssel"). Question: How is it possible to print out the content of the address index (mdr file) ?
