A two stage electronic messaging system and method of use that automatically and accurately responds to user queries (e.g., input documents) using a two stage searching and retrieval system. The two stages system includes fast document-matching techniques (e.g., "weak" search techniques) in combination with more advanced categorization and text-search techniques (e.g., machine learning and other semi-automated techniques). The two stage searching and retrieval system may be used via the Internet, an intranet, LAN or other similar system, and may be used for providing requested information to a user (e.g., customer, employee, customer representative and the like) via a content rich web site, a propriety database or any computer related help system.
