Perhaps you should try some spelling variations:
_quality control » byquality control, quality controls, qouality control
2c reliability » 2 reliability, 20 reliability, 24 reliability
ic reliability » 5 reliability, 2 reliability, 7 reliability
4 safety » 5 safety

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: %(((byquality OR inquality) control) OR (((_quality control) OR (quality control))))%((2c reliability) OR (ic reliability))%4 safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%(((byquality OR inquality) control) or (((_quality control) or (quality control))))%((2c reliability) or (ic reliability))%4 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %(((byquality OR inquality) control) or (((_quality control) or (quality control))))%((2c reliability) or (ic reliability))%4 safety and risk%22*.
