Abstract: A frequently observed difficulty of file access by truncated search keys is the large number of items sometimes retrieved. A simple, efficient means of elaborating upon the truncated search key approach so as to compensate for this difficulty is reviewed and a test of the method described. It is found that the hybrid approach does substantially reduce the number of items retrieved.
