Solr 1.4.1 stats component count not matching facet count for multi
valued field
Hi,
I have a facet field called option which may be multi-valued and
a weight field which is single-valued.
When I use the Solr 1.4.1 stats component with a facet field, i.e.
q=*:*&version=2.2&stats=true&
stats.field=weight&stats.facet=option
I get conflicting results for the stats count result
<long name="count">1</long>
when compared with the faceting counts obtained by
q=*:*&version=2.2&facet=true&facet.field=option
I would expect the same count for either method.
This happens if multiple values are stored in the options field.
It seem that for a multiple values only the last entered value is being
considered in the stats component? What am I doing wrong here?
Thanks,
Johannes

Aha! Thanks, sorry, I'll clarify on my wiki edit.

: Interesting, the wiki page on StatsComponent says "multi-valued fields
: may be slow" , and may use lots of memory.
: http://wiki.apache.org/solr/StatsComponent
*stats* over multivalued fields work, but use lots of memory -- that bug
only hits you when you compute stats over any field, that are faceted by a
multivalued field.

Apparently it should also warn that multi-valued fields may not work at all? I'm going to add that with a link to the JIRA ticket.
