Providing secure search in the presence of document level security (DLS) is so easy in theory that no one has written papers about it until now. In practice, it turns out that while implementing it is (mostly) easy, user expectations of the search experience get in the way of getting it right. A model of the main factors in secure search implementations is presented, together with an analysis of search performance in an experimental DLS environment. Various conclusions are drawn from the results and about the tradeoffs which can be made to optimise for the user's search experience. Note that we do not attempt to describe how a DLS system itself should be implemented - the search system typically must use whatever underlying security mechanisms exist.
