Tatham, you domain model sounds good. So you should do both things. First try to use connected graphs for the agencies and try to traverse from the agency node. If you need to do index lookups you should always use queries that add the agency key (which is in the session) to the lucene query (u

Aman, I think to start with, you probably want to set up indexing on only the interesting aspects of your CMS and documents, not everything. Normally, that leads to a much slimmer storage, and better speed in mutating operations. Given 50K users, the question is how much index-relevant content the
