Abstract: A system and method of dynamic search result permission checking. A system that provides end users the ability to search an index (i.e., Shinydocs Index) built from content from one or multiple source repositories, and only display results for which the user has sufficient permissions at source to view. User credentials are validated “on the fly”, such that these checks are performant across a multiple of possible back-end repositories sequentially or simultaneously. The resultant search results from the Index may be sourced from many disparate repositories, each of which have their own unique permission structure (to view individual items). A method for handling permissions in multiple repositories in a secure (yet performant) fashion in order to only display search results that the end-user is allowed to view based on source system permissions.
