• If you are trying to use Boolean operators, they must be ALL CAPS: %byquality control%((((2c reliability) OR (((((21 reliability) OR (24 reliability))) OR (11 reliability))))) OR (ic reliability))%((23 safety) OR (3 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 (24 reliability))) or (11 reliability))))) or (ic reliability))%((23 safety) or (3 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %byquality control%((((2c reliability) or (((((21 reliability) OR (24 reliability))) or (11 reliability))))) or (ic reliability))%((23 safety) or (3 safety)) and risk%22*.
