Basically you have to index enough information to be able to search (in a single query) and find all documents that a given user has access to read. In the below example there are two fields: DATA: Which contains any data that you want your users to be able to search.... http://java.dzone.com/articles/how-implement-row-level-access#comments Java Server-side authentication authorization lucene search security Frameworks http://java.dzone.com/crss/node/5285 Tue, 07 Oct 2008 15:09:02 -0400 692 2 amccurry http://java.dzone.com/sites/all/files/avatars/picture-312147.jpg Tue, 07 Oct 2008 15:09:02 -0400 amccurry 5285 at http://java.dzone.com http://java.dzone.com/articles/java-restful-clients-and-jax-r RESTful architecture and JAX-RS lead to distributed architectures.
