• If you are trying to use Boolean operators, they must be ALL CAPS: wang tang ((jie yuan) OR (jie hyun)) yi yang xi ((tang zheng) OR (fang sheng)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang tang ((jie yuan) OR (jie hyun)) yi yang xi ((tang zheng) or (fang sheng)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang tang ((jie yuan) OR (jie hyun)) yi yang xi ((tang zheng) or (fang sheng)) ;*.
