• If you are trying to use Boolean operators, they must be ALL CAPS: %byquality control%((((2c reliability) OR (((((21 reliability) OR (2 reliability))) OR (11 reliability))))) OR (ic reliability))%((2((3 safety) OR (5 safety))) OR (((3 safety) OR (5 safety)))) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%byquality control%((((2c reliability) or (((((21 reliability) or (2 reliability))) or (11 reliability))))) or (ic reliability))%((2((3 safety) OR (5 safety))) or (((3 safety) OR (5 safety)))) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %byquality control%((((2c reliability) or (((((21 reliability) or (2 reliability))) or (11 reliability))))) or (ic reliability))%((2((3 safety) OR (5 safety))) or (((3 safety) OR (5 safety)))) and risk%22*.
