Abstract
Method, system, and computer program product for access control for entity search are provided. The method includes: representing entity-relationship data in a conceptual model; representing entities in a search system as documents containing the entity's searchable content and metadata; defining authorization rules for searchers over entities and their relationships; and extending an entity document to include searchable tokens defining the authorization rules. Defining authorization rules may include: identifying query predicate constraints for entity search; and defining searchable tokens as paths for query predicates and permissible searchers; wherein the permissible searchers are permitted access to data based on a query that contains the predicate. Defining authorization rules may further include: defining searchable document files for a free-text predicate with a field name as a token of permissible searchers and the field value as the searchable content.
