fuzzy search

Hi,
I've to retrieve some addresses from a "dirty" database, sometimes the same
address is written in such a different way for axample:

george washington avenue n 44

I can find:

g. washington avenue
washington avenue
g. washington av.
wHashington avAnue ( in case of error)
etc.

I'd like to know if there is a way to retrieve similar results by a fuzzy
search.

Thanks in advance

Giu
