• If you are trying to use Boolean operators, they must be ALL CAPS: doc chieu xanh - ((((hanh trang) OR (thanh trung))) OR (thanh tran)) cua thong cong van luan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc chieu xanh - ((((hanh trang) OR (thanh trung))) or (thanh tran)) cua thong cong van luan ban*".
