I didn't try before, buy now I did and it works fine.

Sorry, my fault. I changed is_in:county by is_in:region in my local copy 
of StyledConverter.java and builtin-tag-list long time ago, that's why 
they appear in my "trunk" maps.

Yes. As a difference to English or German, in Spanish the type of way 
(Calle/Street, Avenida/Avenue, ...) is placed before the name of the 
way. As most urban ways are Calles, directories usually omit it and for 
those which are not calles, the type of way is left or placed at the end 
(Avenida de España / España, Avenida de).

With Garmin genuine maps you don't need to type calle, avenida or 
whatever, just the name of the way, but the type of way is shown in the 
search results, to help choose the right one. If we could get this 
behavior it would improve user experience greatly, as having to type 
calle/avenida/... for any search using gps keyboard/buttons is quite

It's also due to my is_in:county/region change.
