Joel Bernstein commented on LUCENE-10382:
-----------------------------------------
I think Query makes sense as well. I'm a little fuzzy on the cost computation
being discussed. Is this about the decision to do the ANN or fully materialized
KNN? Or is there another cost being discussed that deals with the query being
passed in as a filter?
