• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) hyoung gun hua rein ((yan jiu) OR (yang jie)) ((long shu) OR (tong shui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) hyoung gun hua rein ((yan jiu) or (yang jie)) ((long shu) OR (tong shui)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) hyoung gun hua rein ((yan jiu) or (yang jie)) ((long shu) OR (tong shui)) ;*.
