    摘要: A vicinity search using register point data in a designated area reduces search time. The vicinity search data include at least category information, names of register points and country information. The search device conducts the vicinity search by specifying any one of category information to which the register points belong, names of the register points and country information, or a combination, by option and display. The search device further uses category information with flags representing the presence and absence of the register point data, whereby the register point data are searched by referring to the flags.
