Feature request: Boolean search for contents of one field being the same as contents of another field

Hi! I would like EndNote to be able to find all records in which the contents of one field are the same as the contents of another field, for instance, to find all of the records in which the same person appears as both author and publisher.

In my situation, there are hundreds of such records in my library, but I don’t know all of the people’s names offhand. (I actually want to pull all the patents in which the inventor (=author) is the same as the assignee (=publisher)).

EndNote needs more search flexibility.
