Michael McCandless commented on LUCENE-1421:
--------------------------------------------
I'm only testing groupSort and sort by relevance now in the nightly bench.
I'll add sort-by-title, groupSort-by-relevance cases too, so we test that.
Hmm, though: this content set is alphabetized by title I believe, so it's not
really a good test. (I suspect that's why the TermQuery sorting by title is
faster
bq. Do think when new features are added that these also need be added to this
test suite? Or is this perfomance test suite just for the basic features?
Well, in general I'd love to have wider coverage in the nightly perf test...
really it's only a start now. But there's no hard rule we have to add new
functions into the nightly bench...

> It would be awesome to group search results by specified field. Some
> functionality was provided for Apache Solr but I think it should be done in
