Perhaps you should try some spelling variations:
22quality control » quality control, _quality control, byquality control
2c reliability » 24 reliability, ic reliability, 20 reliability
9 reliability » 4 reliability
2c safety » 2 safety, 22 safety, 23 safety
10 safety » _ safety, a 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 (2 reliability))) OR (((((9 reliability) OR (3 reliability))) OR (5 reliability))))%((2c safety) OR (10 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 (((((9 reliability) OR (3 reliability))) or (5 reliability))))%((2c safety) or (10 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %22quality control%((((2c reliability) or (2 reliability))) or (((((9 reliability) OR (3 reliability))) or (5 reliability))))%((2c safety) or (10 safety)) and risk%22*.
