• If you are trying to use Boolean operators, they must be ALL CAPS: wang liang yang xi ((li gang) OR (li san)) minh ((tong shui) OR (gong hui)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang yang xi ((li gang) or (li san)) minh ((tong shui) OR (gong hui)) ;*".
