• If you are trying to use Boolean operators, they must be ALL CAPS: %forquality control%((((((2c reliability) OR (20 reliability))) OR (21 reliability))) OR (((ic reliability) OR (((2 reliability) OR (5 reliability))))))%((23 safety) OR (11 safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%forquality control%((((((2c reliability) or (20 reliability))) or (21 reliability))) or (((ic reliability) or (((2 reliability) OR (5 reliability))))))%((23 safety) or (11 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %forquality control%((((((2c reliability) or (20 reliability))) or (21 reliability))) or (((ic reliability) or (((2 reliability) OR (5 reliability))))))%((23 safety) or (11 safety)) and risk%22*.
