Method and system for cached document search
A method for servicing document search requests. The method includes receiving, by a document management service, a document search query from a requesting user, identifying, in a document repository, by the document management service, a document that matches the search query, and obtaining a permission level by the document management service, from an access control cache, based on a combination of the requesting user and an access control list required by the document. The access control cache is located on the document management service, and the access control cache is populated using content in an access control repository located on a repository server, separate from the document management service. The method further includes making a determination that the permission level is sufficient and based on the determination, returning the document to the requesting user, as a search result.
