• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22quality control) OR (_quality control))%((((10 reliability) or (5 reliability))) or (ic reliability))%a safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((22quality control) OR (_quality control))%((((10 reliability) or (5 reliability))) or (ic reliability))%a safety and risk%22*.
