Hoss Man commented on SOLR-1782:
--------------------------------
Crux of the problem is in FieldFacetStats's dependency on using StringIndex ...
at least two different code paths use this in the same (broken) way:
Stats.Component.getFieldCacheStats and UnInvertedField.getStats
> stats.facet assumes FieldCache.StringIndex - fails horribly on multivalued
> fields

>
> 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.
