• If you are trying to use Boolean operators, they must be ALL CAPS: %((byquality control) OR (((_quality control) OR (quality controls))))%((((((2c reliability) OR (24 reliability))) OR (20 reliability))) OR (ic reliability))%((4 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))))%((((((2c reliability) or (24 reliability))) or (20 reliability))) or (ic reliability))%((4 safety) OR (_ safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((byquality control) or (((_quality control) or (quality controls))))%((((((2c reliability) or (24 reliability))) or (20 reliability))) or (ic reliability))%((4 safety) OR (_ safety)) and risk%22*.
