• If you are trying to use Boolean operators, they must be ALL CAPS: %((22quality control) OR (forquality control))%((((20 reliability) OR (2 reliability))) OR (ic reliability))%((2c safety) OR (((2 safety) OR (5 safety)))) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22quality control) or (forquality control))%((((20 reliability) OR (2 reliability))) or (ic reliability))%((2c safety) or (((2 safety) or (5 safety)))) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((22quality control) or (forquality control))%((((20 reliability) OR (2 reliability))) or (ic reliability))%((2c safety) or (((2 safety) or (5 safety)))) and risk%22*.
