I'd like to be able to use + (meaning has to have following text) and - (meaning must not have following text) in the search. I'd also like a checkbox to block a response that precisely matches the search, or matches the search with spaces changed to underlines (block auto generated garbage). It would be nice if the search could exclude files with too long names, or files that are too small or large, or files that are too old or new.

I'd also like an egg in my beer.
