Yes, you don't want to hard code permissions into your index - it will give
you headaches.

You might want to have a look at SOLR 1872:
https://issues.apache.org/jira/browse/SOLR-1872 .
This patch provides doc level security through an external ACL mechanism (in
this case, an XML file) controlling a filter query,
This way, you don't need to change the schema - you can even use existing
indexes, and you can change access control without affecting your stored
data.

HTH,
Peter
