• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang liang) OR (yan liang))) OR (yang yang)) tuan china hui ying ka ((long do) OR (long du)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang liang) or (yan liang))) or (yang yang)) tuan china hui ying ka ((long do) or (long du)) ;*.
