• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - ((hanh tranh) OR (hanh trang)) cua khong phan thanh ((toan cau) OR (toan tap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - ((hanh tranh) OR (hanh trang)) cua khong phan thanh ((toan cau) or (toan tap))".
