[jira] [Updated] (SOLR-1782) stats.facet assumes
FieldCache.StringIndex - fails horribly on multivalued fields
[ https://issues.apache.org/jira/browse/SOLR-1782?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hoss Man updated SOLR-1782:
---------------------------
Description:
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.
---
New users interested in mixing stats & facets are encouraged to ignore the stats.facet param and instead combine stats.field with facet.pivot to achieve similar results more efficiently...
