Thank's Jan for your reply. My application has thousands of users and I don't know yet how many of them will use this feature. They can exclude one document from their search results or can exclude 200.000 documents. It's much more natural that they exclude something like 50~300 documents. More than this will be strange.
However, I don't know how cache will work because we have a large number of users who can use this feature. Even that query for user 1 be cached, it won't work for other users. Do you see another solution for this case?
