• If you are trying to use Boolean operators, they must be ALL CAPS: %((((_quality control) OR (quality control))) OR (byquality control))%((((((20 reliability) OR (10 reliability))) OR (2 reliability))) OR (ic reliability))%((((25 safety) OR (5 safety))) OR (((2a safety) OR (a safety)))) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((_quality control) or (quality control))) or (byquality control))%((((((20 reliability) OR (10 reliability))) or (2 reliability))) or (ic reliability))%((((25 safety) or (5 safety))) or (((2a safety) or (a safety)))) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((((_quality control) or (quality control))) or (byquality control))%((((((20 reliability) OR (10 reliability))) or (2 reliability))) or (ic reliability))%((((25 safety) or (5 safety))) or (((2a safety) or (a safety)))) and risk%22*.
