Resolution: Duplicate
> Need group.facet.after = true to get facet counts after group by
> ----------------------------------------------------------------
>
> Key: SOLR-2246
> URL: https://issues.apache.org/jira/browse/SOLR-2246
> Project: Solr
> Issue Type: Bug
> Components: Build
> Affects Versions: 3.1
> Reporter: Bill Bell
> Fix For: 4.0
>
> Original Estimate: 168h
> Remaining Estimate: 168h
>
> 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"
> http://localhost:8983/solr/select?defType=dismax&q=Bill&facet=true&facet.field=gender&group=true&group.field=hgid&ident=true&fl=hgid,gender&sort=gender
> 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.
