• If you are trying to use Boolean operators, they must be ALL CAPS: %((((((22quality control) OR (_quality control))) OR (quality control))) OR (forquality control))%((24 reliability) OR (((ic reliability) OR (5 reliability))))%((2c safety) OR (23 safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((((22quality control) OR (_quality control))) or (quality control))) or (forquality control))%((24 reliability) or (((ic reliability) or (5 reliability))))%((2c safety) or (23 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((((((22quality control) OR (_quality control))) or (quality control))) or (forquality control))%((24 reliability) or (((ic reliability) or (5 reliability))))%((2c safety) or (23 safety)) and risk%22*.
