Hi Slobery,
This thread has some info & tips:

(I apologise if you've already seen it, can't search for your old posts to check) Have you tried simple things like searching at different times of day? This can make a huge difference. Have you ticked 'show all qualities' & 'show all speeds' within your options?
Varying your search terms can make a difference too (eg search just for artist/author etc will give you different results than search for artist and title).
