• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((anh truong) OR (anh thuong)) cua khong duong ((van toan) OR (van tan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((anh truong) or (anh thuong)) cua khong duong ((van toan) OR (van tan)) cau".
