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