• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((hanh trang) OR (hanh trinh)) cua dung ((cong ty) OR (cong san)) toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((hanh trang) OR (hanh trinh)) cua dung ((cong ty) or (cong san)) toan tap*".
