Perhaps you should try some spelling variations:
22quality control » quality control, _quality control, byquality control
ic reliability » 2 reliability, 7 reliability, 8 reliability
4 reliability » 2 reliability
2c safety » 2 safety, 22 safety, 23 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%((((4 reliability) OR (3 reliability))) OR (((ic reliability) OR (5 reliability))))%2c safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22quality control%((((4 reliability) or (3 reliability))) or (((ic reliability) OR (5 reliability))))%2c safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %22quality control%((((4 reliability) or (3 reliability))) or (((ic reliability) OR (5 reliability))))%2c safety and risk%22*.
