Elran Dvir commented on SOLR-2894:
----------------------------------
Brett, thanks for your response.
>>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.
If mincount of 1 is asked for a field, couldn't it be more efficient? Is
mincount of -1 necessary in this case?
>>I would expect the skipRefinementAtThisLevel to be false for the top level
>>pivot facet, and true for each other level. Are you seeing otherwise?
No. You are right.
>>If you were to set a facet.limit of 10 for all levels of the pivot, what is
>>the memory usage like?
The memory usage in this case is about 200 MB.
Thanks again.

> Following up on SOLR-792, pivot faceting currently only supports
> undistributed mode. Distributed pivot faceting needs to be implemented.
