A search site on a network performs information search by a keyword. When a Web page is selected among those detected by the information search, the keyword, a text in the selected Web page and the Web page's address are interconnected and recorded as one search record in a recording device. And then, it is judged whether or not there exist in one or more then one document, any words that match any keywords included in the search records recorded in the recording device. If there exists a word that matches a keyword, the display data to display the document with just a part of the text as least and/or the Web page's address included in the same search record as the keyword, is created, and a job is executed using the display data.
