Perhaps you should try some spelling variations:
22quality control » quality control, _quality control, byquality control
ic reliability » 5 reliability, 7 reliability, 11 reliability
2 reliability » 5 reliability
8 reliability » 5 reliability, 7 reliability
3 reliability » 5 reliability
2 safety » 5 safety, 4 safety, 3 safety
a safety » a safe

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%((2 reliability) OR (((((ic reliability) OR (8 reliability))) OR (3 reliability))))%((2 safety) OR (a safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22quality control%((2 reliability) or (((((ic reliability) OR (8 reliability))) or (3 reliability))))%((2 safety) or (a safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %22quality control%((2 reliability) or (((((ic reliability) OR (8 reliability))) or (3 reliability))))%((2 safety) or (a safety)) and risk%22*.
