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