• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang yanling)) wing hua rents yaw ((tan hong) OR (min jeong)) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) OR (wang yanling)) wing hua rents yaw ((tan hong) or (min jeong)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) OR (wang yanling)) wing hua rents yaw ((tan hong) or (min jeong)) shu ;*.
