• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) ((meng yuan) OR (fang yuan)) li chen zheng ((xin jeong) OR (kin keong)) su ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((meng yuan) OR (fang yuan)) li chen zheng ((xin jeong) or (kin keong)) su ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((meng yuan) OR (fang yuan)) li chen zheng ((xin jeong) or (kin keong)) su ;*.
