Perhaps you should try some spelling variations:
22quality control » quality control, _quality control, byquality control
2c reliability » 20 reliability, 24 reliability, 29 reliability
ic reliability » 5 reliability, 7 reliability, 11 reliability
8 reliability » 5 reliability, 4 reliability, 7 reliability
2 reliability » 5 reliability
3 reliability » 5 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 (((2 reliability) OR (3 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 (((2 reliability) OR (3 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 (((2 reliability) OR (3 reliability))))))%4 safety and risk%22*.
