Andrés de la Peña commented on LUCENE-7086:
-------------------------------------------
Yes, it is a pity. In [our particular use
case|https://github.com/Stratio/cassandra-lucene-index], we can't renounce to
the huge performance improvements due to the usage of
{{EarlyTerminatingSortingCollector}}. Now that the numeric fields have
disappeared, I guess that we don't have other option than using numeric doc
values if we want to upgrade to Lucene 6.0.0. Should we open a new ticket for
fixing this incompatibility within {{SortingMergePolicy}} and point fields, or
is it covered by any other ticket? We can't wait to use the amazing point
fields!
It would also be good to take a look to [the problems paging over search
results|http://permalink.gmane.org/gmane.comp.jakarta.lucene.user/60076] with
{{EarlyTerminatingSortingCollector}}.
