The subject matter of this specification can be implemented in, among other things, a computer-implemented method including receiving a partial query term from a user. The method further includes providing the partial query term to multiple data provider modules. Additionally, the method includes receiving a set of search suggestion items responsive to the partial query term and receiving information identifying a category for each search suggestion item. The method further includes rendering a representation of each search suggestion item, and receiving a user selection identifying one of the search suggestion items from the user interface. And, the method includes rendering a status bar indicating the user selection.

Interactive search querying

Systems, methods, and machine-readable media for selecting an authentication process are disclosed. A system is configured to determine whether a user account on a client device is to be authenticated. If the user account is to be authenticated, the system is configured to transmit a request for a path indicator to an authentication path server. The request includes a user account identifier corresponding to the user account. The authentication path server is configured to select the path indicator based on the user account identifier. The system is further configured to receive the path indicator from the authentication path server, select an authentication process based on the path indicator, and initiate the selected authentication process.

Authentication based on path indicator from a server

One embodiment of the present invention provides a system that authenticates requests between tasks in an operating system. During operation, a first task prepares a request to perform an operation in a second task. In doing so, the first task attaches a credential to the request, and then a trusted entity transfers the request and the credential to the second task. Next, the second task determines whether the credential is valid. If the credential is valid, the second task determines from the credential whether the first task is authorized to request the operation, and, if so, proceeds to perform the operation.

Method and apparatus for authenticating a request between tasks in an operating system

One embodiment of the present invention provides a system that controls accesses to revisions of documents in the presence of a multi-user permissions and ownership model. During operation, the system receives a request to on behalf of a user to access a revision of a document. If the request is directed to a most-recent revision of an existing document, the system uses the multi-user permissions and ownership model to control access to the revision. Otherwise, if the request is directed to a previous revision of the document, the system grants access to the revision only if the user was the owner of the document at the time of the revision.

Handling document revision history information in the presence of a multi-user permissions model

The subject matter of this specification can be implemented in, among other things, a computer-implemented method including receiving from a user a portion of a query. The method further includes providing the portion of the query to multiple data provider modules nearly simultaneously. The method further includes receiving, from ones of the data provider modules, a set of search suggestion items resulting from searching the data sources, each of the search suggestion items including a rank and a relevance value. The method further includes determining a score for each of the search suggestion items by combining the rank and the relevance value for each of the search suggestion items. The method further includes sorting the search suggestion items using the scores. The method further includes presenting the sorted search suggestion items to the user.
