Abstract

A method, system and apparatus comprising a computer program encoded on a computer storage medium for storing a plurality of documents in a computer readable memory, each document of the plurality having a corresponding access Control table (ACL), each ACL defines multiple users who are authorized to access the corresponding document, generates an index based on multiple users, and the index includes multiple partitions, each partition corresponds to a user in multiple users, and for multiple For each of the documents: sort the users among the multiple users, select the user as an index user based on the sort, and store the document in a partition of the index that corresponds to the index user.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to US Provisional Patent Application No. 61 / 452,013, filed March 11, 2011, the disclosure of which is expressly incorporated herein by reference in its entirety. Background technique [0003] This specification generally relates to indexing and searching of documents, access to which is regulated through corresponding Access Control Lists (ACLs). [0004] With the growth of collaborative documents and social networking, more and more content is stored with ACLs specifying the set of people who can access the document. Searching over such a collection of documents presents certain challenges. For example, one user may see a different document than another user. This problem can be solved by adding ACL tokens to documents, each representing a user with permission to access the corresponding document. However, the problem with this approach is that the search system must perform t...
