• If you are trying to use Boolean operators, they must be ALL CAPS: %((byquality control) OR (_quality control))%((((((24 reliability) OR (2.4 reliability))) OR (20 reliability))) OR (ic reliability))%4 safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((byquality control) or (_quality control))%((((((24 reliability) OR (2.4 reliability))) or (20 reliability))) or (ic reliability))%4 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((byquality control) or (_quality control))%((((((24 reliability) OR (2.4 reliability))) or (20 reliability))) or (ic reliability))%4 safety and risk%22*.
