PROBLEM TO BE SOLVED: To efficiently search for a desired website by inputting keywords and text, and using refined keywords. SOLUTION: A user's terminal 10 receives the search webpage of a document search system 20 via a network 30, displays it, and sends the search website including the keywords and the text designated by the user to the document search system 20 via the network 30. The document search system 20 creates keywords based on the keywords and the text designated by the user to search for the desired website, extracts all the websites that contain the keywords, calculates the frequency with which each keyword contained therein appears, then creates a search result webpage which contain as the refined keywords those keywords whose frequencies of appearance are not higher than a certain value, and sends the webpage to the user's terminal 10. The user's terminal 10 displays the search result webpage and performs search again using the refined keywords assessed. COPYRIGHT: (C)2004,JPO
