Document classification systems are valuable tools for searching and retrieving classified documents but can be prohibitively complex and cumbersome for users.A system for the indexing and retrieval of classified documents inserts keywords, titles or definitions of previously applied classifications into the document record and provides the resulting record to a search engine. Searchers are able to retrieve documents by searching on keywords from the classification system without looking up class coding.
