• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((nhieu tang) OR (chieu sach)) - hanh trang ((va dung) OR (xay dung)) cong dan toan cau.
• Adding a wildcard symbol may retrieve word variants: theo ((nhieu tang) or (chieu sach)) - hanh trang ((va dung) or (xay dung)) cong dan toan cau*.
