Hopefully, advanced search parameters get added in the near future. Some things are extremely difficult to find, because of the flood of unwanted results. For example:

I did a search for "Deus Ex" and later "DeusEx"
Both returned massive (400+) results for Wolfgang Amadeus Mozart mp3's, but only 1 result for a Deus_Ex_patch110fm and nothing on Deus Ex itself.

I'm still trying to figure out why the results came back nearly identical on the second search.
