Perhaps you should try some spelling variations:
22quality control » quality control, _quality control, byquality control
2c reliability » 20 reliability, 24 reliability, 21 reliability
ic reliability » 7 reliability, 8 reliability, 11 reliability

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