Let's suppose we have a regular search field body_t, and an internal boolean flag flag_t not exposed to the user.
I'd like
body_t:foo AND flag_t:true
to be an intersection, but if "foo" is a stopword I get all documents
for which flag_t is true, as if the first class was dropped, or if
technically all documents match an empty string.
Is there a way to get 0 results instead?
