• If you are trying to use Boolean operators, they must be ALL CAPS: %((forquality control) OR (byquality control))%((4 reliability) OR (ic reliability))%((((2c safety) OR (22 safety))) OR (((23 safety) OR (3 safety)))) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((forquality control) or (byquality control))%((4 reliability) or (ic reliability))%((((2c safety) or (22 safety))) or (((23 safety) OR (3 safety)))) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((forquality control) or (byquality control))%((4 reliability) or (ic reliability))%((((2c safety) or (22 safety))) or (((23 safety) OR (3 safety)))) and risk%22*.
