• If you are trying to use Boolean operators, they must be ALL CAPS: %((quality control) OR (byquality control))%((2c reliability) OR (((5 reliability) OR (2 reliability))))%((((2c safety) OR (((25 safety) OR (15 safety))))) OR (22 safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((quality control) or (byquality control))%((2c reliability) or (((5 reliability) or (2 reliability))))%((((2c safety) or (((25 safety) OR (15 safety))))) or (22 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((quality control) or (byquality control))%((2c reliability) or (((5 reliability) or (2 reliability))))%((((2c safety) or (((25 safety) OR (15 safety))))) or (22 safety)) and risk%22*.
