PROBLEM TO BE SOLVED: To retrieve a document that eliminates structure information which becomes an obstacle to retrieval and to display with highlight information added to the original structured document when displaying a retrieval result. SOLUTION: This device performs document registration processing with a structured document 102 of a file 114 as an input, produces structured document that is undergone a structure analysis and information for document retrieval and stored them in DBs 105 and 106 respectively. Next, when an input-output device 115 inputs a retrieval condition 103, it analyzes the retrieval condition, reads information for document retrieval and performs retrieval processing 108. It outputs document number information 109 that is hit as a retrieval result and hit range information 110. Display processing first reads a corresponding structure-analyzed structured document 111 from the DB 105 based on the information 109 which is hit by document read processing 107. The processing of document display 112 embeds hit information in the document 111 based on the information 110, produces a structured document 113 for display to which the highlight information is added and shows it. |
