>    Affects Versions: 3.4

> 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.
