• If you are trying to use Boolean operators, they must be ALL CAPS: %((22quality control) OR (((forquality control) OR (_quality control))))%((((24 reliability) OR (2 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 (((forquality control) or (_quality control))))%((((24 reliability) OR (2 reliability))) or (5 reliability))%((2c safety) or (23 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((22quality control) or (((forquality control) or (_quality control))))%((((24 reliability) OR (2 reliability))) or (5 reliability))%((2c safety) or (23 safety)) and risk%22*.
