What are the entities searched by Nominatim? (cannot find relation type=tunnel)
I was searching for this relation by name, but Nominatim finds no results: http://www.openstreetmap.org/relation/5519843#map=15/50.1009/14.4076 - however it seems that Nominatim should be able to [search in relations][1] as well.
(Note that the ways inside this relation have their own, different names, and the relation itself has been named and alt_named this way for many months now.)
Neither the [FAQ][2] nor the [documentation][3] mentions what entities are excluded included/excluded from search; if search, in other words, what specifically is searched. If it's a problem with this specific entity, is there a way to fix it? Or, if `type=tunnel` is not searched, where do I find out what relation types *are* searchable?
