• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yong) OR (dong sign)) ya hua gene ((ying jin) OR (yang jin)) ((tong shui) OR (gong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) or (dong sign)) ya hua gene ((ying jin) or (yang jin)) ((tong shui) OR (gong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) or (dong sign)) ya hua gene ((ying jin) or (yang jin)) ((tong shui) OR (gong hui)) ;*.
