• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho hieu) or (nho hieu)) lang - ((nhan dong) OR (nhan dang)) chua dong cong danh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho hieu) or (nho hieu)) lang - ((nhan dong) OR (nhan dang)) chua dong cong danh toan cau*.
