• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chinh sach)) - ((hanh trang) OR (canh tranh)) va nhung cong danh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chinh sach)) - ((hanh trang) OR (canh tranh)) va nhung cong danh toan cao".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chinh sach)) - ((hanh trang) OR (canh tranh)) va nhung cong danh toan cao*.
