---------------------------------------
Hi Chris,
#1 Yes, I believe the patch applied correctly. Once more, *default* sorting
method is not defined and I didn't see where DistributedFacetPivotTest is
testing the default sort. (I did however see where facet.sort is tested after
facet.sort=count was explicitly specified).
#2 Yes, Per field sorting works with non-distributed pivots. We were working in
a non-distributed configuration up to some point and, until then, per field
sorting worked properly (that was on Solr 4.0)
We also encountered another issue when sorting by count:
There might be a case where 2 of the returned values have the same count. In
such a case, the PivotNamedListCountComparator attempts to sort by value. The
problem is that when facet.missing=true is specified then one of the 2 values
which have the same count may be null (missing) and in such cases the
get("value").toString() operation will fail (NullPointerException).
