• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) ((yan kang) OR (yuan kang)) ((chen when) OR (chen zheng)) change land wang hua ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) ((yan kang) or (yuan kang)) ((chen when) OR (chen zheng)) change land wang hua ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) ((yan kang) or (yuan kang)) ((chen when) OR (chen zheng)) change land wang hua ;*.
