David Bowen commented on SOLR-475:
----------------------------------

We are seeing faceting on multi-valued fields as a significant performance problem, so we'd very much like to see something of this sort.

> Facet multi-valued fields via a counting method (like the FieldCache method) on an un-inverted representation of the field.  For each doc, look at it's terms and increment a count for that term.
