Thanks for your help,
I'll try to be more clear:
- I have some books that have the top category only, and some books that have the top category AND any of the subcategories.
- I need to search which books having the top category don't have any additional subcategories assigned.

So logically it would be: lookup the top category only AND exclude any subcategory, but again, my example and also your examples do not work.

To me this should be correct:

#genre:"=entertainment" AND NOT #genre:"=.entertainment"

but it's not.
