• If you are trying to use Boolean operators, they must be ALL CAPS: %((byquality control) OR (forquality control))%((21 reliability) OR (((ic reliability) OR (2 reliability))))%22 safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((byquality control) or (forquality control))%((21 reliability) or (((ic reliability) OR (2 reliability))))%22 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((byquality control) or (forquality control))%((21 reliability) or (((ic reliability) OR (2 reliability))))%22 safety and risk%22*.
