> Requesting a certain number of rows and setting start parameter to a greater value returns 0 results with grouping enabled.
> For example, requesting:
> http://localhost:8080/solr/web/select/?q=*:*&rows=1&start=2
> (grouping and highlighting are enabled by default)
> I get this response:
> [...]
>       response: {
>           numFound: 117852
>           start: 2
>           docs: [ ]
>       }
>       highlighting: {
>             0938630598: {
>                   title: [ "..." ]
>                   content: [ "..." ]
>             }
>       }
> [...]
> docs array is empty while the highlighted values of the document are present
> Debugging the request in
> org.apache.solr.search.Grouping.Command.createSimpleResponse() at row 534
> [...]
>      int len = Math.min(numGroups, docsGathered);
>       if (offset > len) {
>         len = 0;
>       }
> [...]
> The initial vars values are:
> numGroups = 1
> docsGathered = 3
> offset = 2
> so after the execution len = 0
> I've tried commenting the if statement and this resolves the issue but could introduce some other bugs.
