• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (ho chieu)) xanh - manh ((trung tuan) OR (tran tuan)) dung cong doan va dau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) OR (ho chieu)) xanh - manh ((trung tuan) or (tran tuan)) dung cong doan va dau".
