• If you are trying to use Boolean operators, they must be ALL CAPS: %((22quality control) OR (((((byquality control) OR (forquality control))) OR (quality control))))%((2c reliability) OR (5 reliability))%((23 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 (forquality control))) or (quality control))))%((2c reliability) or (5 reliability))%((23 safety) or (((22 safety) or (2 safety)))) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((22quality control) or (((((byquality control) OR (forquality control))) or (quality control))))%((2c reliability) or (5 reliability))%((23 safety) or (((22 safety) or (2 safety)))) and risk%22*.
