Perhaps you should try some spelling variations:
_quality control » quality control, byquality control, quality controls
5.4 reliability » 5 reliability, 2.6 reliability, 3.3 reliability
14 reliability » 11 reliability, 13 reliability, 3 reliability
ic reliability » 5 reliability, 2 reliability, 7 reliability
2 safety » 5 safety, 4 safety, 3 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: %_quality control%((((5.4 reliability) OR (14 reliability))) OR (ic reliability))%2 safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%_quality control%((((5.4 reliability) OR (14 reliability))) or (ic reliability))%2 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %_quality control%((((5.4 reliability) OR (14 reliability))) or (ic reliability))%2 safety and risk%22*.
