• If you are trying to use Boolean operators, they must be ALL CAPS: %((byquality control) OR (forquality control))%((((((20 reliability) OR (2 reliability))) OR (10 reliability))) OR (ic reliability))%((2 safety) OR (3 safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((byquality control) or (forquality control))%((((((20 reliability) or (2 reliability))) or (10 reliability))) or (ic reliability))%((2 safety) OR (3 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((byquality control) or (forquality control))%((((((20 reliability) or (2 reliability))) or (10 reliability))) or (ic reliability))%((2 safety) OR (3 safety)) and risk%22*.
