Help formulating book search
I would like to generate a list of books in my library for which there is no file in format xxx. For example, if I have an azw book which also exists in epub then I don't want it returned in the results. If another book exists only in azw then I do want it returned.

Logically if I was looking for all books not in e-pub furthest it would be something like:

All books minus format:epub
