Abstract
Systems, computer program products and methods implementing policy enforcement for search engines are described. A policy engine receives a user identifier associated with a search query including one or more query terms. The policy engine receives, from a preprocessor of a search engine, an intermediate representation of the search query. The intermediate representation includes one or more index terms corresponding to the one or more query terms. The policy engine determines, based on a particular policy, if the user is prohibited from accessing data associated with a particular index term. In response, the policy engine modifies the intermediate representation, including negating the particular index term. The policy engine then submits the modified intermediate representation to a query processing module of the search engine, causing the query processing module to exclude content corresponding to the particular index term from search results.
