database should be generic
with the data of street location.
it's the searching part that's smart.
you can do some sort of natural language processing to retrieve relevant keywords from the query string, but it really takes a lot of work to allow intelligent queries.

I think a search like street directory is very simple.
What is does it simply word-by-word or phase-by-phase matching. The good thing about this kind of search is that your vocabulary is very much static. :^P
As for shortest path search, etc., some innovative work is definitely involved. But as there have already been much research in this field, I don't think there is much of a problem either.
It just take time and effort.
