• If you are trying to use Boolean operators, they must be ALL CAPS: hoc tien anh - manh trung cap ((dong duong) OR (((dung dung) OR (dung ung)))) anh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc tien anh - manh trung cap ((dong duong) or (((dung dung) OR (dung ung)))) anh toan cau*".
