Dmitry Kan commented on SOLR-2403:
----------------------------------
Peter: In one of the distributed faceting sessions we have found out, that the
zero facets can be filtered by (undocumented?) facet.zeros parameter. Does
anything change, if you set it to 0 (filtering out zero-facets)?
> Problem with facet.sort=lex, shards, and facet.mincount
> -------------------------------------------------------
>
> Key: SOLR-2403
> URL: https://issues.apache.org/jira/browse/SOLR-2403
> Project: Solr
> Issue Type: Bug
> Components: search
> Affects Versions: 4.0
> Environment: RHEL5, Ubuntu 10.04
> Reporter: Peter Cline
>
> I tested this on a recent trunk snapshot (2/25), haven't verified with 3.1 or
> 1.4.1. I can if necessary and update.
> Solr is not returning the proper number of facet values when sorting
> alphabetically, using distributed search, and using a facet.mincount that
> excludes some of the values in the first facet.limit values.
> Easiest explained by example. Sorting alphabetically, the first 20 values
> for my "subject_facet" field have few documents. 19 facet values have only 1
> document associated, and 1 has 2 documents. There are plenty after that have
> more than 2.
> {code}
> http://localhost:8082/solr/select?q=*:*&facet=true&facet.field=subject_facet&facet.limit=20&facet.sort=lex&facet.mincount=2
> {code}
> comes back with the expected 20 facet values with >= 2 documents associated.
> If I add a shards parameter that points back to itself, the result is
> different.
> {code}
> http://localhost:8082/solr/select?q=*:*&facet=true&facet.field=subject_facet&facet.limit=20&facet.sort=lex&facet.mincount=2&shards=localhost:8082/solr
> {code}
> comes back with only 1 facet value: the single value in the first 20 that had
> more than 1 document.
> It appears to me that mincount is ignored when doing the original query to
> the shards, then applied afterwards.
> Let me know if you need any more info.
> Thanks,
> Peter
