• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wan) yan ((yan yuan) OR (fang yuan)) tan yang yi ((chang hadi) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yan ((yan yuan) or (fang yuan)) tan yang yi ((chang hadi) OR (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) yan ((yan yuan) or (fang yuan)) tan yang yi ((chang hadi) OR (shang hai)) ;*.
