Perhaps you should try some spelling variations:
22quality control » quality control, _quality control, byquality control
24 reliability » 2.4 reliability, 2 reliability, 4 reliability
ic reliability » 2 reliability, 7 reliability, 8 reliability
2 safety » 4 safety, 3 safety

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%((((24 reliability) OR (((3 reliability) OR (5 reliability))))) OR (ic reliability))%((2 safety) OR (((5 safety) OR (_ safety)))) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22quality control%((((24 reliability) or (((3 reliability) or (5 reliability))))) or (ic reliability))%((2 safety) or (((5 safety) OR (_ safety)))) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %22quality control%((((24 reliability) or (((3 reliability) or (5 reliability))))) or (ic reliability))%((2 safety) or (((5 safety) OR (_ safety)))) and risk%22*.
