PROBLEM TO BE SOLVED: To achieve character string retrieval that takes into consideration a character misrecognition in document information read by a scanner, or the like. SOLUTION: A character storing part 104 stores a first character and a second character being an misrecognized character or the like corresponding to the first character, and a derived character string generating part 105 generates a derived character string obtained by replacing the first character included in a retrieval character string with the second character with reference to the character storing part 104. A retrieval part 107 retrieves a retrieval character string and a derived character string from a retrieval object document stored in a document storing part 103, and an output part 113 outputs retrieval results of the retrieval character string and the derived character string.
