• If you are trying to use Boolean operators, they must be ALL CAPS: %((((22quality control) OR (quality control))) OR (byquality control))%((2c reliability) OR (((ic reliability) OR (3 reliability))))%((5 safety) OR (25 safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((22quality control) OR (quality control))) or (byquality control))%((2c reliability) or (((ic reliability) or (3 reliability))))%((5 safety) or (25 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((((22quality control) OR (quality control))) or (byquality control))%((2c reliability) or (((ic reliability) or (3 reliability))))%((5 safety) or (25 safety)) and risk%22*.
