• If you are trying to use Boolean operators, they must be ALL CAPS: tin tan ((cheng wei) OR (cheng hei)) chen ((((yang jie) OR (yang jui))) OR (yang yi)) shang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tin tan ((cheng wei) OR (cheng hei)) chen ((((yang jie) or (yang jui))) or (yang yi)) shang hai ;*".
