• The words AND, OR and NOT may confuse the search; try adding quotes: "fang yuan wang hua rain ((yan jiu) or (((((yang jin) OR (shang jin))) or (ying jin)))) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: fang yuan wang hua rain ((yan jiu) or (((((yang jin) OR (shang jin))) or (ying jin)))) wong sau ;*.
