• If you are trying to use Boolean operators, they must be ALL CAPS: duong van china china als ((((yang yi) OR (yang di))) OR (yang judy)) ((lang hua) OR (wang hui)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "duong van china china als ((((yang yi) or (yang di))) or (yang judy)) ((lang hua) OR (wang hui)) ;*".
