• The words AND, OR and NOT may confuse the search; try adding quotes: "%((_quality control) OR (byquality control))%((ic reliability) or (9 reliability))%3 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((_quality control) OR (byquality control))%((ic reliability) or (9 reliability))%3 safety and risk%22*.
