@UserFriendly I find that the torrent search engine treats multiple words as being conjunctions, i.e., searching on twink kyle turns up all only those torrents with both terms in it. I just did that one and got 7 hits. Putting a minus sign in front of a term (such as twink kyle -orgy) gives 6 results, leaving out the first hit on the previous search that had the word "orgy" in the title. So the take-away message is that a Boolean "and" operator is not needed, and a minus sign prefix will handle a "not" operator. I don't think there's an "or" operator, but perhaps there's some syntax for that.
I haven't tried much with wildcards, but searching for twink kyl* gets additional hits for when the term kyler appears in the title. Note that searching on kyle does not return records with kyler in them.
Intra-website search engines are difficult to implement. I appreciate that the engine here assumes a conjunction with two or more terms. On another torrent site, "twink kyle" would be interpreted as "twink OR kyle," making useful searching almost impossible.
