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 » 2 reliability, 7 reliability, 8 reliability
13 safety » 3 safety, 10 safety, 11 safety
22 safety » 12 safety, 5 safety, 4 safety
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: %((22quality control) OR (((byquality control) OR (quality control))))%((ic reliability) OR (((5 reliability) OR (3 reliability))))%((13 safety) OR (((22 safety) OR (2 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))))%((ic reliability) or (((5 reliability) or (3 reliability))))%((13 safety) or (((22 safety) OR (2 safety)))) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((22quality control) or (((byquality control) or (quality control))))%((ic reliability) or (((5 reliability) or (3 reliability))))%((13 safety) or (((22 safety) OR (2 safety)))) and risk%22*.
