• If you are trying to use Boolean operators, they must be ALL CAPS: wing tan yang xi ((li gang) OR (liu gang)) minh ((tong shui) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing tan yang xi ((li gang) OR (liu gang)) minh ((tong shui) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing tan yang xi ((li gang) OR (liu gang)) minh ((tong shui) or (zhong zhi)) ;*.
