• If you are trying to use Boolean operators, they must be ALL CAPS: wang dan ((sudan ta) OR (sudan gas)) chen ((((ying jin) OR (yang xi))) OR (yang jun)) dong sin ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dan ((sudan ta) OR (sudan gas)) chen ((((ying jin) or (yang xi))) or (yang jun)) dong sin ;*".
