Perhaps you should try some spelling variations:
22quality control » quality control, _quality control, byquality control
2c reliability » 2 reliability, 24 reliability, 21 reliability
20 reliability » 2 reliability, 10 reliability, 24 reliability
ic reliability » 2 reliability, 5 reliability, 9 reliability
2 safety » _ safety, a safety, 4 safety
5 safety » _ safety, a 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 (20 reliability))) OR (ic reliability))%((((2 safety) OR (5 safety))) OR (2((2 safety) OR (5 safety)))) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22quality control%((((2c reliability) OR (20 reliability))) or (ic reliability))%((((2 safety) or (5 safety))) or (2((2 safety) or (5 safety)))) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %22quality control%((((2c reliability) OR (20 reliability))) or (ic reliability))%((((2 safety) or (5 safety))) or (2((2 safety) or (5 safety)))) and risk%22*.
