Right, here is how it is at the moment, say you search
"Bit Torrent"
in to the Bit Che box, it submits Bit Torrent to the search engines and then collects their results. Often this returns lots of crap, so it filters stuff out that have in the title "Bit" AND "Torrent", this is unless you have "include description searches" enabled.
You can filter things out like this for example:
"Stargate -Atlantis"
Which will return all results with Stargate in the title, but automatically remove all results with Atlantis in the title. You can also filter things out permanently from a filter.txt in the Bit Che directory.
