• If you are trying to use Boolean operators, they must be ALL CAPS: wang huang ying end ((plant during) OR (gland during)) risk ((hong shu) OR (cong shu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang huang ying end ((plant during) OR (gland during)) risk ((hong shu) or (cong shu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang huang ying end ((plant during) OR (gland during)) risk ((hong shu) or (cong shu)) ;*.
