<p>Candidate facilities, which have been limited by a search by name, are further limited to facilities which are located within a specific narrowed search range. First, area codes of administrative areas and mesh codes of mesh areas which are both within the specific narrowed search range are searched for. The candidate facilities which belong to the searched administrative areas are extracted by comparing data records of the candidate facilities which have been limited by the search by name with the searched area codes. Further, the candidate facilities which belong to the searched mesh areas are extracted by comparing data records of the candidate facilities which have been extracted on the basis of the area codes with the searched mesh codes. Finally, the facilities within the narrowed search range are limited by comparing position coordinates of the candidate facilities which belong to the searched mesh areas with the narrowed search range.</p> |
