An more extensive search function so we can better filter by number of instruments

By that I mean, lets say I wanna see all the scores that aren't for a single instrument, but the way it is now I can only search through all the number 2s, then the 3s, then the 4s...

I want to search all scores above or equal to 2 instruments, or 5, or 7 for example, and as a bonus I could exclude all above 12 or something like that, because I don't want SO many, but maybe someone else would...
