Access control predicates associated with a search query, including fixed-width and/or variable-width tokens, are received from the search engine, and are formatted in a machine-readable binary format to generate a single byte array. A pre-sorted memory index structure associated with the single byte array is generated, by sorting the access control predicates according to their token width. The pre-sorted memory index structure is merge joined with an uninverted terms index that includes a sorted list of all terms in a field associated with the search query, and a document index mapping each document identifier (ID) to a term ordinal for a specific field."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Scalable fine grained access control within a search engine","description":"A system and method for providing fine-grained access control in a search engine.
