An information search system is provided. The information search system is capable of searching a target content based on meta information provided by a broadcast station, in which a reception device makes an inquiry toward a directory service server based on a meta information reference ID accompanying meta information coming from the broadcast station so that a meta information group is derived for reference by the meta information reference ID. Also, another inquiry is made toward a content service server based on address information or a keyword of the content included in sub meta information in the meta information group so as to perform a search for any desired content.
