• If you are trying to use Boolean operators, they must be ALL CAPS: %((((((byquality control) OR (_quality control))) OR (((quality controls) OR (quality control))))) OR (forquality control))%((2 reliability) OR (9 reliability))%((22 safety) OR (_ safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((((byquality control) or (_quality control))) or (((quality controls) OR (quality control))))) or (forquality control))%((2 reliability) or (9 reliability))%((22 safety) or (_ safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((((((byquality control) or (_quality control))) or (((quality controls) OR (quality control))))) or (forquality control))%((2 reliability) or (9 reliability))%((22 safety) or (_ safety)) and risk%22*.
