Perhaps you should try some spelling variations:
22quality control » _quality control, forquality control, quality controls
byquality control » _quality control, forquality control, quality controls
ic reliability » 5 reliability, 7 reliability, 8 reliability
2 reliability » 3 reliability, 5 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: %((((22quality control) OR (byquality control))) OR (quality control))%((2 reliability) OR (ic reliability))%2c safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((22quality control) OR (byquality control))) or (quality control))%((2 reliability) or (ic reliability))%2c safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((((22quality control) OR (byquality control))) or (quality control))%((2 reliability) or (ic reliability))%2c safety and risk%22*.
