Unfortunately there's no documentation on this yet, but maybe Christmas 
or the new year will bring us some time to get at it.

The current state is like that:

EXT:solr supports access restricted pages, so that you won't get results 
that you're not allowed to see. Currently there's a drawback though that 
under certain constellations it happens that some access restricted 
results are shown multiple times if a user belongs to multiple groups.
This is due to the way how we implemented the feature. Currently it 
looks like we have to go back and do it like indexed search, indexing a 
page for each combination of groups found on a page. However, while this 
is a problem for indexed search performance and index size wise, it's 
not an issue for Solr as we can handle way bigger indexes than would 
ever be possible with indexed search.

Currently we're also working on improving this situation by determining 
which groups are used for the content elements on a page and then find 
the least dominator from that which applies to the page.

So support for access restrictions on content element level is underway too.


Long story short: We currently support FE groups but we'll have to adopt 
the indexed search implementation of FE group support to fix some issues 
we found with our current solution. However, this is not an issue 
performance wise for Solr as it is for indexed search.


Hope that helps
Ingo
