This invention provides a system and method for responding to a user query. An identifier identifies an answer to a user query based on data in one or more structured data collections. A search engine in communication with the identifier searches, based on the answer, a systematically-generated, automatically-updated index of files to identify a file associated with the answer. A ranker in communication with the search engine ranks the identified files. A generator in communication with the search engine generates a response to the query based on a result of the searching. In one application, the system is used to provide an answer portal. |
