Alex Parvulescu commented on JCR-2959:
--------------------------------------
I've added a new test suite that includes the changes to the 2.3 performance
tests in revision #1161481.
So we can compare the 2 sort implementations. (it will also help see the
evolution of the new impl).
> SQL2 QueryEngine should use Lucene for sort

> Currently all SQL2 queries with "order by" expression are sorted with

> Lucene should be used for sorting hits instead.
