• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan tuan) OR (yan yuan)) china won ((((yang jie) or (yang jin))) or (wang ning)) zong hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan tuan) OR (yan yuan)) china won ((((yang jie) or (yang jin))) or (wang ning)) zong hai ;*.
