  • Patent number: 7505973
    Abstract: Methods and computer-readable media provide for efficient paging of search results in accordance with the access rights of a user. According to various implementations, a request for a search query results in a calculated number of search results being retrieved and analyzed for user access rights. As documents having user access rights are located, session state information corresponding to the number of located documents having user access rights and to the number of analyzed documents required to locate the number of documents having user access rights is maintained. This information is used to dynamically alter the number of subsequent documents that are retrieved in order to fill a page of results. This minimizes redundant determinations of user access rights and minimizes the number of documents required to be retrieved and analyzed in order to fulfill a search query request.
