Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing a plurality of documents in computer-readable memory, each document of the plurality of documents having a corresponding access control list (ACL), each ACL defining a plurality of users that are authorized to access a respective document, generating an index based on the plurality of users, the index comprising a plurality of partitions, each partition corresponding to a user of the plurality of users, and, for each document of the plurality of documents: ranking the users of the plurality of users, selecting a user as an indexing user based on the ranking, and storing the document in a partition of the index, the partition corresponding to the indexing user.

Efficient indexing and searching of access control listed documents

A computer-implemented user interface method include displaying an image on a graphical user interface of a mobile computing device, receiving a first user input indicating an intent to perform a zooming operation on the graphical user interface, transitioning the mobile computing device into a zooming mode in response to the user input, sensing motion of the mobile computing device in one or more of a plurality of directions, correlating the sensed motion in one or more of a plurality of directions with either a zooming in or a zooming out zooming direction, and changing a zoom level of the display of the image on the graphical user interface to correspond to the correlated zooming direction.

Methods, systems, and apparatus, including computer program products, for searching indexed and non-indexed content. One method includes updating an index of a corpus of resources from time to time to generate an updated index for use by a search engine. Change data specifying changes made by users affecting resources are recorded. An index search result based on the most-recently updated index is received in response to a user search query. The change data is searched to identify any changes to the resources made by the user that relate to the search query and if any such changes are found, a revised search result is generated from the changes and the index search result and provided to the user as a response to the first query.
