• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (ha tinh)) - hanh truong ((quan nhung) OR (cua nhung)) cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (ha tinh)) - hanh truong ((quan nhung) OR (cua nhung)) cong dan than cau".
