Abstract
A searching device of the present invention searches a sub-facility included in a large compound facility based on information stored in the device. A large compound facility is first searched, and then a sub-facility included in the large compound is searched if a user specifies the sub-facility. The user may specify the sub-facility to be searched by inputting certain keywords even when he/she does not know the exact name of the sub-facility. The searching device may be advantageously included in a navigation system such as a car navigation system. The specified sub-facility included in a large compound facility may be set as a target destination and a driving route from a starting point to the target destination can be exactly calculated.
