Perhaps you should try some spelling variations:
_quality control » quality control, byquality control, quality controls
2c reliability » 2 reliability, 24 reliability, 20 reliability
ic reliability » 2 reliability, 11 reliability, 13 reliability
5 reliability » 3 reliability, 2 reliability
8 reliability » 3 reliability, 2 reliability, 4 reliability
9 reliability » 3 reliability, 2 reliability, 4 reliability
4 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: %_quality control%((2c reliability) OR (((((((ic reliability) OR (5 reliability))) OR (8 reliability))) OR (9 reliability))))%4 safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%_quality control%((2c reliability) or (((((((ic reliability) OR (5 reliability))) or (8 reliability))) or (9 reliability))))%4 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %_quality control%((2c reliability) or (((((((ic reliability) OR (5 reliability))) or (8 reliability))) or (9 reliability))))%4 safety and risk%22*.
