• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang wang hui ((dan yang) or (tan yang)) yi ((chang ha) or (((hong ong) OR (hong kong)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang wang hui ((dan yang) or (tan yang)) yi ((chang ha) or (((hong ong) OR (hong kong)))) ;*.
