• If you are trying to use Boolean operators, they must be ALL CAPS: %((((byquality control) OR (quality controls))) OR (forquality control))%((11 reliability) OR (ic reliability))%((22 safety) OR (2 safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((byquality control) or (quality controls))) or (forquality control))%((11 reliability) or (ic reliability))%((22 safety) OR (2 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((((byquality control) or (quality controls))) or (forquality control))%((11 reliability) or (ic reliability))%((22 safety) OR (2 safety)) and risk%22*.
