GOAL:
What is Index Bracketing
FIX:
Having selected one or more indexes to satisfy a query, Progress tries immediately to isolate the smallest necessary index subset so as to return as few records as possible. Careful query design can increase the opportunities for bracketing, thereby preventing Progress from scanning entire indexes and examining all records.
