SOLR Permissions / Filtering Results depending on Access Rights

Question

For example I have Documents A, B, C. User 1 must only be able to see Documents A, B. User 2 must only be able to see Document C. Is it possible to do it in SOLR without filteri

Answer 1

There are no built in mechanisms for Solr that I am aware of that will allow you to control access to documents without maintaining the rights in the metadata. The approach outlined by aitchnyu seems reasonable if you keep it a true role level and not assign user specific permissions to a document. That way you can assign roles to users and this will grant them the ability to see documents in the index. Granted you will still need to reindex documents when the roles change, but hopefully you can identify most of the needed roles ahead if time and reduce the need for frequent reindexing.
