More than one library

[Huebi]

Please post some example searches that you would use so I have something to work with.

What I currently have in mind is grouping the files by genre. Grouping different genres together is not a problem, but I would also like to have something like "everything without audiobooks", like this

Code:

Genre !Audiobooks

or also everything without classics.

Code:

Genre !Classical

It doesn't need to be more complicated than that for me at the moment

Or full scope: 

Code:

Select *
from library
where genre is not "Classical"
  and gnere is not "AudioBooks"
  and year is between 1972 and 1978

Ok, just kidding
