A document management system which can flexibly cope with an access right range of a secret document while efficiently sharing document data is provided. The document management system has a data server, a full-text search service server connected to the LAN, and a fire wall arranged between the full-text search service server and the data server. When the user wants to refer to document/document image data accumulated in the data server, a client terminal designates a character train included in the document/document image data to be referred to, thereby performing the searching process. When the user wants to designate an access-limited character train as a search word, a password for the access-limited character train is simultaneously designated. When the access-limited character train and the password are not designated, the document including the access-limited character train is not displayed as a search result but is seen as if the document including the access-limited character train does not exist.
