Abstract
Recognizing that a search target must be particular identifying words, words that are shared by a plurality of sets of destination data are stored as search keywords appended to individual sets of destination data that serve as the search targets. In execution of a search for a destination, keywords that in part match the input characters are displayed as selectable keys. It is possible to reduce user input operations by creating a menu of relevant keywords. Reduction in the number of user operations becomes possible by selecting keywords having three or more characters by a total of two operations, that is, the input of at least one character to retrieve a narrowed down group of keywords and selection of one of the retrieved keywords.
