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