StatsComponent and multi-valued fields

[dbashford <db...@hotmail.com>]

Running 1.4.1.

I'm able to execute stats queries against multi-valued fields, but when
given a facet, the statscomponent only considers documents that have a facet
value as the last value in the field.

As an example, imagine you are running stats on "fooCount", and you want to
facet on "bar", which is multi-valued.  Two documents...

1)
fooCount = 100
bar = A, B, C

2) 
fooCount = 5
bar = C, B, A

stats.field=fooCount&stats=true&stats.facet=bar

I would expect to see stats for A, B, and C all with sums of 105.  But what
I'm seeing is stats for C and A with sums of 100 and 5 respectively.

Is this expected behavior?  Something I'm possibly doing wrong?  Is this
just not advisable?

Thanks!

I'm not sure ... just reading it yesterday night ...
but isn't the unapplied patch from Harish
https://issues.apache.org/jira/secure/attachment/12400054/SOLR-680.patch
what you want?

Peter.

It's a known bug ... StatsComponent's "Faceted Stats" make some really 
gross assumptions about the Field...
