Abstract
An apparatus stores one or more document information of which access right is managed by an access right management apparatus, and generates an index of stored document information. The apparatus receives user identification information, and sends the user identification information, and information for identifying document information of which index has not been generated to the access right management apparatus. The apparatus receives access right information associated with the user from the access right management apparatus, and generates index of the identified document information based on the received access right information.
