• If you are trying to use Boolean operators, they must be ALL CAPS: %((22quality control) OR (((forquality control) OR (_quality control))))%((((21 reliability) OR (20 reliability))) OR (((ic reliability) OR (9 reliability))))%((2_ safety) OR (_ safety)) AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22quality control) or (((forquality control) OR (_quality control))))%((((21 reliability) or (20 reliability))) or (((ic reliability) or (9 reliability))))%((2_ safety) or (_ safety)) and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((22quality control) or (((forquality control) OR (_quality control))))%((((21 reliability) or (20 reliability))) or (((ic reliability) or (9 reliability))))%((2_ safety) or (_ safety)) and risk%22*.
