Wrong number of found documents (grouping)

Hello!

Much fewer documents are displayed for me than are available in grouped ..
-> numFound.

Is a trick maybe necessary to display the correct number of found documents
in grouping mode and multi core search.

Thanks

Mike

The "group.ngroups" parameter is the only thing I am aware of that is 
related to getting correct counts back in grouping.

https://solr.apache.org/guide/6_6/result-grouping.html#ResultGrouping-RequestParameters

A warning, group.ngroups=true will make a grouping query a lot slower.

Can you elaborate on the EXACT problem you're seeing so we can determine 
whether I am headed down the right path?

There is also the group.limit parameter, which depending on exactly what 
you are seeing, could be what you need to add/change.

Thanks,
Shawn
