This is what I've found in some limited test. I have a map with the
following nodes:
    is_in:A Coruna,Galicia,Spain
    is_in:Naron,A Coruna,Galicia,Spain
    is_in:A Coruna,Galicia,Spain
    name:San Sadurniño
Searching in the Cities tab, if I introduce any of the three names above
in the City field and leave blank the others fields, search result is
one entry in the form name, name, A CORUNA, ESP. If I also introduce "A
Coruna" in the State/Province field, I get six entries for Cerdido
(Cerdido, Cerdido, A CORUNA, ESP), two for Pedroso and one for San
Sadurniño. Finally, if I leave blank City field and introduce "A Coruna"
as State/Province, I get 6 Cerdido+2 Pedroso+1 San Sadurniño
Map is built with  --location-autofill=1
I hope this information is of some usefulness.

Sad to say that most of the names listed in my maps have nothing to do
with actual regions. I'm afraid a lot of work on osm data is required.
