Someone else was recently asking a similar question (or maybe it was you but worded differently :) ).
Putting user level security at a document level seems like a recipe for pain. Solr/Lucene don't do frequent update well...and being highly optimized for query, I don't blame them. Is there any way to create a series of roles that you can apply to your documents? If the security level of the document isn't changing, just the user access to them, give the docs a role in the index, put your user/usergroup stuff in a DB or some other system and resolve your user into valid roles, then FilterQuery on role. -- View this message in context: http://lucene.472066.n3.nabble.com/document-level-security-indexing-searching-techniques-tp946528p946649.html Sent from the Solr - User mailing list archive at Nabble.com.
