A posted text search system, a posted text search device, a posted text search method, and a computer program that make it possible to appropriately search for only a posted text that includes information required by a user are provided. In the case where a guide route is set in a communication terminal 7, a viewing request for a posted text is transmitted to a posted text search server 3. When the viewing request is received, the posted text search server 3 determines whether or not a congestion factor facility, which is a facility that causes congestion, is located around the guide route. In the case where it is determined that a congestion factor facility is located around the guide route, a first closer intersecting road and a second closer intersecting road, which are roads that are located on the user side with respect to the congestion factor facility and that intersect the guide route, are acquired. A combination of "name of the first closer intersecting road or the second closer intersecting road" and "congestion" is set to a search word. A search is made for a posted text that includes the set search word from texts posted on a computer network. |
