• If you are trying to use Boolean operators, they must be ALL CAPS: ((du yang) OR (dong hoang)) ala yu zheng zong cheng ((wong siu) OR (wong sau)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((du yang) or (dong hoang)) ala yu zheng zong cheng ((wong siu) OR (wong sau)) ;*".
