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