Terrance A. Snyder commented on SOLR-2614:
------------------------------------------

Starting work on this now - I'll try to combine it in a way that is similar to the facet.pivot
component and work out from there.

>  Is it possible to get stats (like Stats Component: min ,max, sum, count,
> missing, sumOfSquares, mean and stddev) from numeric fields inside
> hierarchical facets (with more than one level, like Pivot)?
>  I would like to query:
> ...?q=*:*&version=2.2&start=0&rows=0&stats=true&stats.field=numeric_field1&stats.field=numeric_field2&stats.pivot=field_x,field_y,field_z
>  and get min, max, sum, count, etc. from numeric_field1 and
> numeric_field2 from all combinations of field_x, field_y and field_z
> (hierarchical values).
>  Using stats.facet I get just one field at one level and using
> facet.pivot I get just counts, but no stats.
>  Looping in client application to do all combinations of facets values
> will be to slow because there is a lot of combinations.
>  Thanks a lot!
> this  is  very  import,because  only counts value,it's no use for sometimes.
> please add   stats with pivot  in solr 4.0 
> thanks a lot
