Subject Re: Public/Private data in Solr :: Metadata or ?
Date Tue, 18 Oct 2016 21:18:18 GMT
You might want to talk to Kevin Waters or look at some of the work being
done with the graph plugin. It's being used to model permissions with Solr.
It's a bit of normalization within Solr whereby you could localize updates
to a users shared-with document. Kevin can probably talk more intelligently
than I can about it.
