• If you are trying to use Boolean operators, they must be ALL CAPS: %((byquality control) OR (_quality control))%((((20 reliability) OR (((21 reliability) OR (5 reliability))))) OR (((ic reliability) OR (9 reliability))))%((23 safety) OR (13 safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((byquality control) or (_quality control))%((((20 reliability) or (((21 reliability) or (5 reliability))))) or (((ic reliability) or (9 reliability))))%((23 safety) OR (13 safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((byquality control) or (_quality control))%((((20 reliability) or (((21 reliability) or (5 reliability))))) or (((ic reliability) or (9 reliability))))%((23 safety) OR (13 safety)) and risk%22*.
