The posted web page is displayed on the display screen of the mobile phone terminal 10.

  Thus, in the information search system, desired search conditions can be registered as reservation search targets. The information search server 20 periodically performs robot type search after such reservation search is registered. At this time, the information search server 20 extracts related search conditions such as matching or similar to the search conditions from the reservation search database based on the search conditions for performing the robot type search this time. When the information search server 20 performs a robot type search and finds a web page or content corresponding to the extracted search condition, the information search server 20 creates a list thereof and sends the extracted search condition to the reserved search target e-mail. For example, as shown in FIG. 26, an e-mail in which a new search result is registered is transmitted to the address.

  The search information server 20 responds when the user of the mobile phone terminal 10 selects the link information 126 provided in the received e-mail and describing the URL for browsing the search result. As shown in FIG. 27, a web page composed of a search result list is displayed on the display screen of the mobile phone terminal 10 as a search result.

  In this way, in the information search system, by performing a reserved search by the information search server 20, even if the search result for the input search condition is 0, the search condition for the search condition will be displayed later. It is possible to cope with a case where a new search result is found.

  In the information search system, the search result is not limited to 0 cases for the input search condition, but when the search result is found by the search through the web page shown in FIG. For example, as shown in FIG. 28, a web page provided with link information 127 for guiding to the reservation search registration screen together with the search result is displayed on the display screen of the mobile phone terminal 10, and the FIG.
