• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((22quality control) or (_quality control))) or (quality control))%((24 reliability) or (((ic reliability) OR (5 reliability))))%2 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((((22quality control) or (_quality control))) or (quality control))%((24 reliability) or (((ic reliability) OR (5 reliability))))%2 safety and risk%22*.
