Website: Pitch-Range Filter for Keyboard Music?

I don't know how (im)practical it would be, but I think it would be nice to have a pitch-range filter when searching for piano music. Different models of pianos and keyboards have different ranges, so it might be helpful to input a specific range when searching, and the results would contain music within that range.
Granted, I'm a complete novice at piano, but it's annoying when a piece I'd like to learn has notes outside the range of my keyboard.

Just a thought....
