20100332524 | Name Searching Apparatus - In a destination search function, a narrow search function for displaying the number of hits and next candidates, when an index having data on the number of hits and the next candidate characters is held and a narrow search is speeded up referring to the index during a search. Only about a narrow search result in which the hit numbers is large such that a search time is elongated when referring to numbers, indexes in which the number of hits and next candidate characters as the narrow search result are computed are previously stored. At the time of performing the narrow search, when the number of hits is small and the numbers and the next candidates are not registered, the numbers is counted. When the number of hits and the next candidate characters are registered in the index, the narrow search results are computed by using its registration result. | 12-30-2010 |
