• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - thanh dung ((tai nhung) OR (thi nhung)) cong doan ((phan dau) OR (phan tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - thanh dung ((tai nhung) or (thi nhung)) cong doan ((phan dau) OR (phan tu))".
