• If you are trying to use Boolean operators, they must be ALL CAPS: wai yan wang hua gain ((((wang yang) OR (((yang lin) OR (yang li))))) OR (yang jie)) dang hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai yan wang hua gain ((((wang yang) or (((yang lin) OR (yang li))))) or (yang jie)) dang hai ;".
• Adding a wildcard symbol may retrieve word variants: wai yan wang hua gain ((((wang yang) or (((yang lin) OR (yang li))))) or (yang jie)) dang hai ;*.
