摘要

PROBLEM TO BE SOLVED: To solve the problem in which an accurate position of a retrieval character string in a document obtained as a retrieval result or a character string corresponding thereto cannot be determined. SOLUTION: A retrieval character string input from an input part 14 is subjected to normalization by a preprocessing part 16, and retrieval is executed to the retrieval character string subjected to the normalization. In a retrieved document, position information of the first character of the retrieval character string or a character string corresponding thereto and position information of the final character of the retrieval character string or the character string corresponding thereto are acquired.
