Abstract
Architecture for security trimming results in a document version environment. Versioned documents are stored with metadata that includes associated access rights. All versions are searched using multiple user accounts of varying levels of access that correspond to the document versions. Result sets are returned for each user account and trimmed during a merge process by considering the user rights associated with each of multiple versions of objects or documents. Each document metadata includes a scope ID that defines security rights for that document. In a two-version document (major and minor) implementation, successive queries are run as a user with rights to all minor versions, and as a user with rights to all major items, but not the minor items. The result sets are merged into a final trimmed result set by examining the rights to each item in the versioned sets that align with rights of the current user.
