Description

Harish Agarwal reported this in solr user mailing list : http://search-lucene.com/m/QTPaoTJXV1

It is east to re-produce with default example solr setup. Following types are added example schema.xml. And exampledocs are indexed.

 <field name="cat" type="string" indexed="true" stored="true" docValues="true" multiValued="true"/>
  <field name="popularity" type="int" indexed="true" stored="false" docValues="true" multiValued="true"/>

When docValues="true" and multiValued="true" are used at the same time, StatsComponent throws :

ERROR org.apache.solr.core.SolrCore  – org.apache.solr.common.SolrException: Type mismatch: popularity was indexed as SORTED_SET
