Anarkii commented on SOLR-1782:
-------------------------------
Is there any update on this issue? Or if Wojtek's fix would be merged into the
trunk? I'm trying to do a stats.facet on a field which contains multiple
tokens, and have the same issue resulting out of getStringIndex. Say, I'm doing
a stats.facet on a field "tags", which can contain multiple tokens...only one
of the tags is being considered.
> 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.
