Most of my fiction books are one of these two categories. Right now I'm trying to tag the 'nots' in Calibre, but there are times I want to do other searches (mysteries not by Agatha Christie or Dorothy Sayers).

The long-press filtering can do "x and y" or "not x and y". To do something more complicated for the first expression (the "x") you must manually enter the expression into the search box and let CC do a scan. For example, in theory you could enter the following into the search box
Code:
not tags:mystery and not "tags:science fiction"
I say "in theory" because I discovered a bug in "not" processing that makes the above not work. I will release a fix in a week or so. In the meantime you could enter the following equivalent expression (see de Morgan's theorem for why it is equivalent)
Code:
not (tags:mystery or "tags:science fiction")
