27. A text search method for deciding en bloc whether or not a plurality of user-designated search terms exist in a text composed of characters expressed in the form of character codes, characterized in that character codes are fetched from said text to output only those character codes that are included in said search terms by extracting said character codes, referred to as filtering; matching is performed en bloc for deciding whether or not said search terms exist in the string of said character codes as outputted; and synchronizing between said filtering and said matching for buffering differences in processing speed while transferring data from said filtering to said matching.

A text search method set forth in claim 27, characterized in that in said selective outputting, a particular delimiter code is outputted only when said leading character flag and trailing character flag corresponding to character codes as inputted are "OFF" and when said leading character flag and trailing character flag corresponding to character codes inputted immediately before are "ON".
