• If you are trying to use Boolean operators, they must be ALL CAPS: %((22quality control) OR (byquality control))%((((2c reliability) OR (24 reliability))) OR (((ic reliability) OR (5 reliability))))%((2 safety) OR (10 safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22quality control) OR (byquality control))%((((2c reliability) or (24 reliability))) or (((ic reliability) or (5 reliability))))%((2 safety) or (10 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((22quality control) OR (byquality control))%((((2c reliability) or (24 reliability))) or (((ic reliability) or (5 reliability))))%((2 safety) or (10 safety)) and risk%22*.
