Yeah, I specifically find ebay search to be very powerful and useful as well. It accepts (keywordA, keywordB) as an "or" syntax, -badkeyword as "not" syntax, and filtering for most of their internal functionality (eg auction/buy-it-now format, item location, item price, etc).

The one that they're missing that I really wish they would include is "multi item BIN" formats. People will list a $1 item so that they're the first result that comes up, and then the item you're looking for is high priced. The prices are in fact so high that I go out of my way to try and exclude these items using "not" keywords, setting a minimum price, and filtering to US only, which collectively get most of them.

I have a lot of saved searches for "rare" items that only get listed infrequently, or for items that I'm waiting to come down in price.

The contrast between the way those two sites handle their search is stark.
