Perhaps you should try some spelling variations:
_quality control » quality control, byquality control, qouality control
quality controls » quality control, qualite controle, quality concepts
ic reliability » 2 reliability, 5 reliability, 9 reliability
23 safety » 3 safety, 2 safety, 13 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) OR (quality controls))%((3 reliability) OR (ic reliability))%23 safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((_quality control) OR (quality controls))%((3 reliability) or (ic reliability))%23 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((_quality control) OR (quality controls))%((3 reliability) or (ic reliability))%23 safety and risk%22*.
