Perhaps you should try some spelling variations:
22quality control » quality control, _quality control, byquality control
2c reliability » 2 reliability, 20 reliability, 24 reliability
ic reliability » 2 reliability, 7 reliability, 11 reliability
8 reliability » 2 reliability, 7 reliability
4 safety » 5 safety

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22quality control%((2c reliability) OR (((((ic reliability) OR (((8 reliability) OR (3 reliability))))) OR (5 reliability))))%4 safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22quality control%((2c reliability) or (((((ic reliability) or (((8 reliability) OR (3 reliability))))) or (5 reliability))))%4 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %22quality control%((2c reliability) or (((((ic reliability) or (((8 reliability) OR (3 reliability))))) or (5 reliability))))%4 safety and risk%22*.
