Patent ID: 8204877

Claim:
A point of interest (POI) search device, comprising: a static POI data storage unit that stores static POI data, the static POI data being data on a prescribed POI; an added POI data storage unit that stores added POI data, the added POI data being POI data to be added as a new search target or POI data for changing POI data contained in the static POI data; a deleted POI data storage unit that stores deleted POI data, the deleted POI data being data for identifying POI data not subjected to a search in the static POI data; a search keyword setting unit that sets a search keyword used in searching the static POI data and/or the added POI data with respect to at least a POI name and a POI category; a POI search unit that computes a number of hits of POI data as a search result which matches the search keyword with respect to at least the static POI data and the added POI data; and a computation switch unit that computes the number of POI data matching the search keyword from among the static POI data, and that switches a computation processing of computing the number of POI data as a search result in the POI search unit according to the computed number of POI data; wherein the computation switch unit switches, if the number of hits of the POI data matching the search keyword computed from the static POI data is not more than a prescribed threshold, the computation processing to a processing of using the deleted POI data when the POI search unit computes the number of hits of the POI data as the search result to be presented to a user, and switches, if the number of hits of the POI data is more than the prescribed threshold, the computation processing to a processing of not using the deleted POI data when the POI search unit computes the number of hits of the POI data as the search result to be presented to the user.
