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