• If you are trying to use Boolean operators, they must be ALL CAPS: %((((((byquality control) OR (_quality control))) OR (quality controls))) OR (forquality control))%((2 reliability) OR (((ic reliability) OR (8 reliability))))%((22 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))) or (forquality control))%((2 reliability) or (((ic reliability) OR (8 reliability))))%((22 safety) or (_ safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((((((byquality control) or (_quality control))) or (quality controls))) or (forquality control))%((2 reliability) or (((ic reliability) OR (8 reliability))))%((22 safety) or (_ safety)) and risk%22*.
