37. A text search method set forth in claim 32, characterized in that in said filtering, a value indicating "ON" is set as a flag for concatenate character codes, referred to as leading concatenate character codes, of a leading portion of the search term designed previously with a value indicating "OFF" being set as a flag to other character codes, referred to as trailing concatenate character codes, then said leading concatenate character codes in those included in said search term, while a value indicating "ON" is set as a flag to the other concatenate character codes, and that said leading concatenate character flag and said trailing concatenate character flag are referenced in correspondence to n concatenate character codes inputted sequentially to thereby output concatenate character codes to said character string matching only when the relevant leading concatenate character flag as read out is "ON" and selectively output n input concatenate character codes to said character string matching only when either the relevant leading concatenate character flag or designated concatenate character flag is "ON" before both of said leading concatenate character flag and said trailing concatenate character flag become "OFF", when said leading concatenate character flag is once assumed "ON".
38. A test search method set forth in claim 37, characterized in that in said selective outputting, a particular delimiter code is outputted to said character string matching means only when said leading character string flag and trailing character string flag corresponding to the n concatenate character codes as inputted are "OFF" and when said leading character string flag and said trailing character string flag corresponding to n concatenate character codes as inputted immediately before are "ON".
