Subject [jira] [Resolved] (SOLR-1782) stats.facet assumes FieldCache.StringIndex - fails horribly on multivalued fields
Date Tue, 03 Feb 2015 15:41:37 GMT

     [ https://issues.apache.org/jira/browse/SOLR-1782?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hoss Man resolved SOLR-1782.
----------------------------
       Resolution: Won't Fix
    Fix Version/s: 5.0

I'm marking this as resolved:won't fix since SOLR-6351 has provided an alternative solution
that works better and supports more options then stats.facet ever did.

> the StatsComponent assumes any field specified in the stats.facet param can be faceted
using FieldCache.DEFAULT.getStringIndex.  This can cause problems with a variety of field
types, but in the case of multivalued fields it can either cause erroneous false stats when
the number of distinct values is small, or it can cause ArrayIndexOutOfBoundsException when
the number of distinct values is greater then the number of documents.
