• If you are trying to use Boolean operators, they must be ALL CAPS: %((forquality control) OR (_quality control))%((((2c reliability) OR (21 reliability))) OR (((ic reliability) OR (2 reliability))))%4 safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((forquality control) or (_quality control))%((((2c reliability) OR (21 reliability))) or (((ic reliability) or (2 reliability))))%4 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((forquality control) or (_quality control))%((((2c reliability) OR (21 reliability))) or (((ic reliability) or (2 reliability))))%4 safety and risk%22*.
