1. A method for retrieving data from a set of natural language texts, the method comprising the steps of:
- storing the units of the natural language texts and fixed-length codes into a conversion-code table relating each unit uniquely to each code;
constructing a coded-text database which stores a set of coded texts produced by converting the units of the natural language texts into the relating fixed-length code using the conversion-code table while maintaining information concerning unit order of the natural language texts; and
retrieving coded-texts from the coded-text database using the fixed-length code.
