Sorry, i was a little vague here.
I am searching only for audio files, that's what i selected over on the left of the window, and that's all i get in the results. No problems with seeing other kinds of files, doesn't happen.
It's as if the search doesn't consider where i enter the keywords. If i put 'talk talk' in the artist field, i get (it seems) almost anything with the word 'talk' in it, no matter where it appears.
For example, the search mentioned above gets me:

Talking Heads
Tevin Campbell -- Can We Talk
The Black Crows -- She talks to angels
Talk dirty to me
Tracy Chapman -- Talkin bout a revolution
(i hate tracy chapman!)

There's no discrimination between song title, artist, etc.
Sure i could filter, but ... filter like this for every search i want to do? That's a clumsy workaround.
What's the point of having different search fields (artist, song title etc) when it seems they are mixed together?

Thanks.
