Choose only 2-3 attributes which are the most important to you at first. If there are too many results, you can finetune your search by adding further attributes. If you are searching for an attribute combination and the database cannot find any matching tracks it will ignore more and more attributes from right to left in the search interface, starting with tempo, then arrangement, then instruments and so on.
