摘要
A document search apparatus capable of an index-type search and a scan-type search performs a search in a combination of the two search types while compensating for the disadvantages of the two search types with each other. A search query for index-type search and a search query for scan-type search are constructed based on a search query consisting of a logical formula of keywords. Then, a character 2-gram for performing an index search is set to shorten the whole search time, and the index-type search is performed. Finally, a scan-type search is performed on this search result of the index-type search.
