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