• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wan) ((yan yuan) OR (gan guan)) li chen chan ming ((kong su) OR (rong su)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) ((yan yuan) or (gan guan)) li chen chan ming ((kong su) OR (rong su)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) ((yan yuan) or (gan guan)) li chen chan ming ((kong su) OR (rong su)) ;*.
