• Performing a fuzzy search may retrieve terms with similar spellings: kai zong cheng ((y chen) OR (yu chen)) ((yang xi) or (yang yi)) shang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: kai zong cheng ((y chen) OR (yu chen)) ((yang xi) OR (yang yi)) shang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "kai zong cheng ((y chen) OR (yu chen)) ((yang xi) or (yang yi)) shang hai ;*".
