• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu trach - ((anh manh) OR (anh anh)) cua van cong thanh ((toan cau) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: theo chu trach - ((anh manh) or (anh anh)) cua van cong thanh ((toan cau) or (toan cao))*.
