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