• If you are trying to use Boolean operators, they must be ALL CAPS: %22quality control%((((20 reliability) OR (10 reliability))) OR (ic reliability))%2 safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22quality control%((((20 reliability) OR (10 reliability))) or (ic reliability))%2 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %22quality control%((((20 reliability) OR (10 reliability))) or (ic reliability))%2 safety and risk%22*.
