Bill Bell updated SOLR-2246:
----------------------------

           Description: 
Please add group.facet.after = true option. 

The use case is that we want the facets numbers to count only the 1st item in 
each group if using the default limit of 1. This first item is what we show on 
the page, 
and facets needs to reflect what is shown on the page. The facet field should 
add the subsections when using "&group.facet.after=true"

 asc

hgid:1
gender:M

hgid:1
gender:F

hgid:1
gender:M

-- when grouping this returns 1 row, with gender:F.

hgid:2
gender:F

hgid:2
gender:M

-- when grouping this returns 1 row, with gender:F.

hgid:3
gender:M

-- when grouping this returns 1 row, with gender:M.

        </lst>
        <lst name="facet_dates"/>
        <lst name="facet_ranges"/>
    </lst>
</lst>

After group.field=<field> we want the facet counts to reflect the documents 
that have been grouped.





  was:
Please add group.facet.after  = true option. 

After group.field=<field> we want the facets to be reduced by the grouping.



    Remaining Estimate: 168h
     Original Estimate: 168h

> Need group.facet.after = true to get facet counts after group by
