Part of it depends on what you mean by "threshold". If it's just the number of matches, then fine. But if you're talking score here, be very, very careful. Scores are not an absolute measure of anything, they only tell you that "for _this_ query, the docs should be order this way".
So I'd advise against any "query chain" based on scores as the threshold, if that's what you mean by "threshold".
