• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (chieu tinh)) - nhan ((dang luan) OR (hang luan)) duong trong tac toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu tinh)) - nhan ((dang luan) OR (hang luan)) duong trong tac toan cau".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu tinh)) - nhan ((dang luan) OR (hang luan)) duong trong tac toan cau*.
