• If you are trying to use Boolean operators, they must be ALL CAPS: cho ((hieu manh) OR (chieu sang)) - hanh chinh ((vat dung) OR (va duong)) cong dan toan cau.
• Adding a wildcard symbol may retrieve word variants: cho ((hieu manh) or (chieu sang)) - hanh chinh ((vat dung) or (va duong)) cong dan toan cau*.
