Let's say you have 100000 documents in your index that match your query but only 10 of them the user has access to:
A basic implementation will return the top, let's say 1000, documents and then do the more expensive access check on each of them. Most of the time, you've now eliminated all of your search results.
Your search must be access aware to do a reasonable job of pre-filtering the content to documents the user has access to, at which point you then can apply post-filtering with the "100% sure" access check.
