The collapse count is the number of matching entries which the matcher
saw.  If you set the check_at_least parameter of Enquire::get_mset() to
at least database.doc_count(), then the matcher will check all documents
in the database, and the collapse counts will be exact.  However,
matching will be slower because you're preventing it from terminating
early.
