• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - nang sang ((qua dung) OR (cuong dung)) cong san ((thanh cac) OR (thanh bac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - nang sang ((qua dung) or (cuong dung)) cong san ((thanh cac) OR (thanh bac))*".
