• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((yan yuan) or (yan guan)) xi ((cheng change) OR (change change)) making among thin ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((yan yuan) or (yan guan)) xi ((cheng change) OR (change change)) making among thin ;*.
