Shai Erera commented on LUCENE-4858:
------------------------------------
bq. Now that SORTER_ID_PROP is added to the diagnostics, maybe that
SORTED_DIAGNOSTICS_PROP is redundant?
Good point.
bq. Nothing prevent you from wrapping eg. a TotalHitCountCollector inside it
Well, I think that's the point where we're trying to protect the user too much.
I suggest that we commit what we have, maybe clarify the javadocs to explain
better what early termination means, and fix/make it more robust when users
actually trip on something.
bq. I'll work on improving documentation as well.
Thanks. Would you mind to get rid of SORTED prop in that patch too?
