• If you are trying to use Boolean operators, they must be ALL CAPS: %((((22quality control) OR (_quality control))) OR (forquality control))%((2 reliability) OR (29 reliability))%((2c safety) OR (22 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))%((2 reliability) or (29 reliability))%((2c safety) or (22 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((((22quality control) OR (_quality control))) or (forquality control))%((2 reliability) or (29 reliability))%((2c safety) or (22 safety)) and risk%22*.
