Posted text search systems, methods, and programs acquire an expected travel route for a mobile body and determine whether a congestion factor facility, which is a facility that causes congestion, is located around the expected travel route. The systems, methods, and programs acquire, when it is determined that the congestion factor facility is located around the expected travel route, a closer intersecting road, which is a road that is located on the side of the mobile body with respect to the congestion factor facility and that intersects the expected travel route and acquire a name of the closer intersecting road as a search target name. The systems, methods, and programs set a search word from a character string of the acquired search target name and extract a posted text that corresponds to the set search word from texts posted on a computer network.
