First Claim
1. A search system comprising:
- a terminal device for requesting a management server to search a position at which a target whose location is desired to be searched exists by sending search request information, which includes at least the information of the target and the feature of the target, to the management server;
the management server for receiving the search request from the terminal device and issuing target information, which includes at least target identification information for identifying respective targets and the feature information of the respective targets, to a mobile communication device based on the search request information; and
at least one mobile communication device which comprises means for obtaining the feature information and means for analyzing and comparing the obtained feature information and the target information issued by the management server and means for measuring the position of the mobile communication device and searches the position at which the feature information of the target whose position is requested to be searched exists based on the target information issued by the management server,wherein when the mobile communication device detects the existence of the feature information of the target whose position is requested to be searched, the mobile communication device notifies the management server of the detected position information and the time information together with the feature information of the target; and
the management server notifies the terminal device of the position information of the target estimated based on the detected position information, the time information and the feature information of the target and causes the terminal device to output the information.

Abstract
When a mobile terminal device detects the existence of the feature information of an article whose position is requested to be searched, it notifies an article management server of the detected position information and the time information together with the feature information of the article, and the article management server notifies a terminal device of the position information of the target estimated based on the detected position information, the time information and the feature information of the target and causes the terminal device to output the information. With this operation, when an article and the like are searched, they can be effectively searched even if they are not provided with a wireless tag, and thus a probability of discovery can be enhanced.
