• If you are trying to use Boolean operators, they must be ALL CAPS: %((byquality control) OR (qouality control))%((((2c reliability) OR (2 reliability))) OR (((ic reliability) OR (5 reliability))))%((25 safety) OR (5 safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((byquality control) or (qouality control))%((((2c reliability) or (2 reliability))) or (((ic reliability) OR (5 reliability))))%((25 safety) or (5 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((byquality control) or (qouality control))%((((2c reliability) or (2 reliability))) or (((ic reliability) OR (5 reliability))))%((25 safety) or (5 safety)) and risk%22*.
