• If you are trying to use Boolean operators, they must be ALL CAPS: wang dan yang hua shen ((chang ma) OR (chang ha)) ((hong shu) OR (wong shiu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dan yang hua shen ((chang ma) or (chang ha)) ((hong shu) OR (wong shiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang dan yang hua shen ((chang ma) or (chang ha)) ((hong shu) OR (wong shiu)) ;*.
