Search result with grouping activated delivers wrong numFound values.
---------------------------------------------------------------------

                 Key: SOLR-2817
                 URL: https://issues.apache.org/jira/browse/SOLR-2817
             Project: Solr
          Issue Type: Bug
    Affects Versions: 3.4
            Reporter: bronco
            Priority: Blocker


I use the 3.4 brach of solr for grouping my results, but obviously there is something wrong in my eyes. If I activate the grouping functionality I get the expected results. In my case for example 4 rows, but the the numFound value says it has 26 results. 

This result is used by the Apache Solr Library in Drupal to calculate the correct pager on my website. Now I get a search result page with 4 results and a confused pager with 3 more steps to not existing search pages.

I try a lot of things including using a facet and all the other suggested things by google but I couldn't change the numFound value to the correct one in my case.

If I not use the group.main=true setting including a facet I get in the facet conclusion the correct values of found results but it also say matches 6 (numFound=6). The Apache Solr Library make it nesessary to use the group.main=true setting because without this value the library is not able to parse the resultset. So I get always an empty website without any results even solr answers correctly.

Is it somehow possible to change the numFound value to the correct one of the group count result. I think nobody groups a field and shows maybe 10 entries which belong to the request and tell the user we have 200 other things which are not interesting you. But I have to tell you... 

Any help is apreciated to get some understanding why solr delivers me this numFound result and how to fix this issue.
