Patent number: 11496444Abstract: Technologies are disclosed for enforcing access control to resources of an indexing system using resource paths. Before performing a search for resources, access control is performed. By determining the resource paths that the user is authorized and/or unauthorized to access before performing the search, the search engine returns resources that the user is authorized to access instead of returning resources that the user may not be authorized to access. Before submitting a search query to a search engine an augmented search query is generated. The augmented search query includes one or more filter rules (which may be referred to herein as “filters”) that specify the resource paths to include or exclude from the search. The augmented search query limits the search to resources that the user is authorized to access.Type: GrantFiled: June 24, 2019Date of Patent: November 8, 2022Assignee: Amazon Technologies, Inc.Inventors: Yong Yuan, Saurabh Kumar Singh, Sachin Bangalore Raj
