Hi Elran,
Having a mincount of -1 for the shards is correct. The reason is that while a
given shard may have a count lower than mincount for a given term, the
aggregate total count for that value when combined with the other shards could
exceed the mincount, so we do need to know about it. For example, consider a
mincount of 10. If we have 3 shards with a count of 5 for a term of "Boston",
we would still need to know about these because the total count would be 15,
and would be higher than the mincount.
I would expect the skipRefinementAtThisLevel to be false for the top level
pivot facet, and true for each other level. Are you seeing otherwise?
If you were to set a facet.limit of 10 for all levels of the pivot, what is the
memory usage like?
