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