• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu tinh)) - hanh trung tuan ((hung cuong) OR (hung luong)) san toan cau.

• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu tinh)) - hanh trung tuan ((hung cuong) OR (hung luong)) san toan cau*.
