• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - hanh dinh cua tong cong ((((manh toan) OR (anh tuan))) OR (thanh toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - hanh dinh cua tong cong ((((manh toan) OR (anh tuan))) or (thanh toan)) cau*".
