A system that provides secure autocomplete searching receives an autocomplete query from a user, the autocomplete query including a prefix of a search phrase, and retrieves security information of the user. The system searches one or more prefix indexes to find a set of matching objects, where the matching objects each include associated object security information. The system excludes matching objects that the user is not authorized to access from the set of matching objects based on the object security information and the user security information. The system then returns the set of matching objects to the user. |
