Abstract
An apparatus for searching document information in response to a search request from a client is disclosed. When a document file is designated as a search condition by a search condition designating unit of the client, the unit causes contents of the designated file to be transmitted via a network. A document search unit of a search machine forms a keyword based on the file contents transmitted from the search condition designating unit, and searches similar documents from an index or selection of important words extracted from search target documents provided in a search database.
