      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"

      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.

      <lst name="facet">
          <lst group="hgid">
            <lst name="facet_counts">
              <lst name="facet_queries"/>
              <lst name="facet_fields">
      			<lst name="gender">
      				<int name="M">1</int>
      				<int name="F">2</int>
      			</lst>
              </lst>
              <lst name="facet_dates"/>
              <lst name="facet_ranges"/>
            </lst>
          </lst>
      	<!-- could have other ones -->
      	<!-- this is the total counts -->
          <lst name="facet_counts">
              <lst name="facet_queries"/>
              <lst name="facet_fields">
      			<lst name="gender">
      				<int name="M">4</int>
      				<int name="F">2</int>
      			</lst>
              </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.
