Look at the collapse module https://cwiki.apache.org/confluence/display/solr/Collapse+and+Expand+Results. It can the same thing as group.
If you want to get counts/facets from before the collapse, tag the collapse statement use the exclude tags tags in your json facets (there's an equivalent for non json facets). I think the default nullpolicy is different from grouping too, but you can change it to be the same. I've not been able to get 2 collapses to work on my version of Solr. But collapse + group works and you can get 2 levels. Not being able to do multiple collapses appears to be a bug (it sorta works). I recall there being JIRA case somewhere stating it was fixed in some version. So you may be able to do as many levels as you like if you upgrade/already run a very recent version of Solr.
