• If you are trying to use Boolean operators, they must be ALL CAPS: %((_quality control) OR (byquality control))%((((24 reliability) OR (((2.2 reliability) OR (12 reliability))))) OR (2 reliability))%2 safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((_quality control) or (byquality control))%((((24 reliability) or (((2.2 reliability) OR (12 reliability))))) or (2 reliability))%2 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((_quality control) or (byquality control))%((((24 reliability) or (((2.2 reliability) OR (12 reliability))))) or (2 reliability))%2 safety and risk%22*.
