Perhaps you should try some spelling variations:
_quality control » quality control, byquality control, quality controls
2c reliability » 2 reliability, ic reliability, 20 reliability
24 reliability » 2.4 reliability, 2 reliability, 4 reliability
9 reliability » 3 reliability, 2 reliability, 4 reliability
5 reliability » 3 reliability, 2 reliability
3 safety » a safety, 5 safety, 4 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: %_quality control%((((2c reliability) OR (24 reliability))) OR (((9 reliability) OR (5 reliability))))%((3 safety) OR (_ safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%_quality control%((((2c reliability) or (24 reliability))) or (((9 reliability) or (5 reliability))))%((3 safety) OR (_ safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %_quality control%((((2c reliability) or (24 reliability))) or (((9 reliability) or (5 reliability))))%((3 safety) OR (_ safety)) and risk%22*.
