• If you are trying to use Boolean operators, they must be ALL CAPS: %((((22quality control) OR (_quality control))) OR (forquality control))%((((2c reliability) OR (24 reliability))) OR (ic reliability))%((22 safety) OR (12 safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((22quality control) OR (_quality control))) or (forquality control))%((((2c reliability) or (24 reliability))) or (ic reliability))%((22 safety) or (12 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((((22quality control) OR (_quality control))) or (forquality control))%((((2c reliability) or (24 reliability))) or (ic reliability))%((22 safety) or (12 safety)) and risk%22*.
