• The words AND, OR and NOT may confuse the search; try adding quotes: "%22quality control%((((((2c reliability) OR (24 reliability))) or (((2 reliability) or (3 reliability))))) or (ic reliability))%((((2c safety) or (2a safety))) or (((23 safety) or (a safety)))) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %22quality control%((((((2c reliability) OR (24 reliability))) or (((2 reliability) or (3 reliability))))) or (ic reliability))%((((2c safety) or (2a safety))) or (((23 safety) or (a safety)))) and risk%22*.
