1. A method of serving a search result that includes an access controlled document comprising:

  • receiving a query from a computing device;

    searching an index on one or more servers to obtain results to the query, wherein the index includes publicly accessible documents and access controlled documents;

    obtaining a persistent access token that permits the verification of access to one or more of the access controlled documents;

    ranking the results but subjecting only a subset of the results to an authorization check;

    using the persistent access token to verify authorization to access the subset of the access controlled documents from the ranked result, wherein an access controlled document is a document that is not publicly accessible; and

    continuing to evaluate lower ranked access controlled documents, if needed based on the authorization check, to return a result list to the computing device.
