摘要： A character string retrieval system retrieves a character string corresponding to a retrieval key input thereto from a text file including a plurality of characters. The system includes an index indicating position data identifying a position of each of characters in the text file and indicating next character data identifying either a character or a character string formed of a plurality of characters arranged next to each of the characters in the text file, a selecting unit for selecting a first character from characters forming the character string corresponding to the retrieval key, a determining unit for determining, with reference to said index, whether or not a character or a character string next to the first character, selected by said selecting unit, in the retrieval key is equal to a character or a character string identified by the character data corresponding to the first character; and output unit for outputting a retrieval result when said determining unit determines that a character or a character string next to the first character in the retrieval key is equal to a character or a character string identified by the character data corresponding to the first character, the retrieval result being obtained based on the position data corresponding to the first character in said index.
