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