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