• The words AND, OR and NOT may confuse the search; try adding quotes: "lung can ghana china hea ((yang jie) or (((yang jun) or (((yang jui) OR (yang xi)))))) wang zhi ;~".
• Adding a wildcard symbol may retrieve word variants: lung can ghana china hea ((yang jie) or (((yang jun) or (((yang jui) OR (yang xi)))))) wang zhi ;*.
