Neelesh Shastry updated SOLR-4411:
----------------------------------
Description:
The parameter facet.mincount provides a good way of filtering counts less than
a given number in a faceted query. facet.maxcount would be the upper bound
counterpart for this. Currently I'm doing this inside FacetComponent,by
filtering the facet counts explicitly, but this is expensive. I would like to
know the challenges in implementing this feature both in sharded/non-sharded
environments. Willing to implement the feature with tests.
On first pass, it looks like I need to change the facet count algos for
termenum, fieldcache, uninverted as well as DistribFieldFacet.
