Website alteration?

[Green Monster]

I note that when picking a catergory, Ie "Settings", then entering a keyword ie "oval" it returns about 340 items many of which are not settings, would it be a good idea to have a keyword search per catergory just to save a bit of time in finding items?
I am looking for a 9 x 7 oval stone setting but the first items shown are oval lobsters etc.

cheers

Forget I said anything, there is of course the "narrow search" feature..doh!
