PURPOSE: To provide a data processor in which the time required for updating data for retrieval is short. CONSTITUTION: A dictionary data generation means 3 generates dictionary data 2 for a code string 1 to be a retrieval object by a key string. Also, a dictionary tree generation means 5 generates a dictionary tree 4 based on the dictionary data 2. Further, a text data generation means 7 generates text data 6 based 011 the code string 1. Also, a text tree generation means 9 generates a text tree 8 based on the text data 6. Further, a retrieval means 10 retrieves a rear part string for which the entire part or a part of the key string is a front part string based on the dictionary tree 4 and the text tree 8. Further, a change means 11 changes the code string 1 and an updating means 12 updates the dictionary data 2, the dictionary tree 4, the text data 6 and the text tree 8 of the code string relating to the change based on the contents of the change. |
