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
