How the permission checking impact the performance during a search?
Suppose you have a large repository with a lot of documents (1 M). Suppose that a user has visibility on few documents (100). What happen when the user makes a generic search (ie for the category invoice) that hit 10.000 documents?
Alfresco performs the search finding the 10k documents and after check the permissions for each one or the permission checking is integrated in the lucene search?
Exists any method to estimate if the query will return a large result and will take some time?

thanks
Andrea
