PROBLEM TO BE SOLVED: To provide an information search system, an information search device, an information search method and a computer program capable of reducing a processing load required for searching for point information.SOLUTION: The information search system is configured to acquire a guide route from a start point to a destination, to set plural search reference points on the guide route, to calculate aggregation coordinates for collecting coordinates adjacent to the search reference point by masking the coordinate at the search reference point using a mask value, to extract point information where the coordinate masked by the mask value coincides with the aggregation coordinate from the plural point information, and to provide the extracted point information. |
