• If you are trying to use Boolean operators, they must be ALL CAPS: thien hieu lang - lanh manh ((cua thong) OR (cua khong)) cong ((dang toan) OR (dan toan)) tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thien hieu lang - lanh manh ((cua thong) or (cua khong)) cong ((dang toan) OR (dan toan)) tap*".
