Searching for a street in Ragusa, Italy, with Nominatim, the place is displayed with a confusing reference to "Catania CTR Zone 2" and "Ragusa Ibla" while it should only display the town name: "Ragusa".

nominatim indexes Catania CTR Zone 2 as locality, which is wrong.

correction, it indexes it because

"-- any feature more than 5 square miles is probably worth indexing"
functions.sql, placex_insert()

maybe worth indexing, but using it as part of an address is something different.

The way is tagged:

aeroway = ctr

which is an undocumented tag which even I don't understand.

Nominatim makes the assumption that it is an airport boundary and that this train station is within that boundary. Personally I think airspaces don't belong in the dataset and if they do they certainly shouldn't be tagged as aeroway = ctr.

Data error - please fix the data instead.

Found this documented on the wiki: http://wiki.openstreetmap.org/wiki/Airspace

As per this I'm going to delete these airspace ways which will resolve the problem.
