Note however that there is no 1:1 relationship between place=... and 
admin_level - e.g. something on admin_level 8 could be a place=city or 
place=town, or (in Germany) something on admin_level can be a 
place=state or place=city capital=yes or so.

It might be worth studying the Nominatim code, or asking the Nominatim 
coders, how they deal with this - they might have interesting insight.
