 Nominatim computes the address from two sources in the OpenStreetMap data:
 from administrative boundaries and from place nodes. Boundaries are the more
 useful source. They precisely describe an area. So it is very clear for

+Nominatim assigns each map feature one country. Those outside any administrative
