<p>PROBLEM TO BE SOLVED: To provide a chart management server which is capable of full text search of a chart with only a title area as the object without preliminary setting of the title area by a user.SOLUTION: When a chart is registered, a title registration unit 130 acquires position coordinates of a title item comprising a preliminarily determined character string out of character strings registered with a chart search index 160 to determine a title area and registers the title area as title data 170. In response to a chart search request from a user terminal 200, the position coordinates of the title area are acquired from the title data 170, and meanwhile, a full text search unit 121 uses search keywords included in the chart search request to search the chart search index 160 and acquires a pertinent search keyword and its position coordinates, and a chart search unit 120 uses the search result to search for a chart including the search keyword in the title area.</p> |
