• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((minh trang) OR (thanh trung)) cua ((dang phuong) OR (bang phuong)) van toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((minh trang) or (thanh trung)) cua ((dang phuong) OR (bang phuong)) van toan cau*".
