• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - ((anh tang) OR (nhanh lang)) cua nhung ((cong dan) OR (cong san)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((anh tang) or (nhanh lang)) cua nhung ((cong dan) OR (cong san)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((anh tang) or (nhanh lang)) cua nhung ((cong dan) OR (cong san)) toan cau*.
