Looking at this again, I'm not sure if what I wrote is actually true. I do seem to get the best matches at the top for most queries.

What triggered my observation above was that a local fact (in my case local.assms) got shown at the end of the list, even though it was the best match. Any idea where this could be coming from? I don't remember any special treatment of local facts compared to others, and looking (very) briefly over the code, I didn't see any.

The example I used was (on HOL/Main)

lemma x:
  assumes "2 <= card S"
  show P

using the find_theorems interface after the assumes with the search "_ <= card _" gives me a list of 15 matches, where the local assumption is the last, but the otherwise best (smallest) match is the first.

In any case, this doesn't seem to be a problem specific to the interface, but to the processing on the ML side.
