Michael McCandless commented on LUCENE-8791:
--------------------------------------------
{quote}In my opinion, rescorers should be used on the very top hits only.
{quote}
Is the concern that this rescorer optionally accepts {{ExecutorService}} to
distribute the work across threads?
Maybe we could just add another ctor *not* taking {{ExecutorService}} for those
use cases that want to run single-threaded?
