The filters thing is a general problem with search because it's really difficult to distinguish between:

1. X is a must-have; and

2. X, Y and Z are all on my wish list so I want to see the most matches first.

Even Google is kind of awkward with this. It used to be you could add + to a term (before the Google+ boondoggle). Now you have to quote things.

Other sites will do so for specific criteria. Take a real estate portal: the bedroom numbers will be absolute but it may include surrounding areas to what you specify. Or there may be an option to turn that off.

It is frustrating but I can see why sites err on the side of caution by treating it as a ranking suggestion vs a hard requirement.
