Michael McCandless created LUCENE-4622:
------------------------------------------
Summary: TopKFacetsResultHandler should tie break sort by label
not ord?
Key: LUCENE-4622
URL: https://issues.apache.org/jira/browse/LUCENE-4622
Project: Lucene - Core
Issue Type: Bug
Components: modules/facet
Reporter: Michael McCandless
EG I now get these facets:
{noformat}
Author (5)
Lisa (2)
Frank (1)
Susan (1)
Bob (1)
{noformat}
The primary sort is by count, but secondary is by ord (= order in which they
were indexed), which is not really understandable/transparent to the end user.
I think it'd be best if we could do tie-break sort by label ...
But talking to Shai, this seems hard/costly to fix, because when visiting the
facet ords to collect the top K, we don't currently resolve to label, and in
the worst case (say my example had a million labels with count 1) that's a lot
of extra label lookups ...
