Perhaps you should try some spelling variations:
byquality control » forquality control, quality controls, qualify control
_quality control » quality controls, qualify control, quality contol
qouality control » quality controls, qualify control, quality contral
10 reliability » 3 reliability, 5 reliability, 2 reliability
ic reliability » 5 reliability, 2 reliability, 7 reliability
2c safety » 2 safety, 22 safety, 23 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) OR (((((_quality control) OR (qouality control))) OR (byquality control))))%((10 reliability) OR (ic reliability))%2c safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((quality control) or (((((_quality control) OR (qouality control))) or (byquality control))))%((10 reliability) or (ic reliability))%2c safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((quality control) or (((((_quality control) OR (qouality control))) or (byquality control))))%((10 reliability) or (ic reliability))%2c safety and risk%22*.
