• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sang) OR (chieu sach)) - ((nhanh thang) OR (nhanh thanh)) va dung cong van tuan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) or (chieu sach)) - ((nhanh thang) OR (nhanh thanh)) va dung cong van tuan ban".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) or (chieu sach)) - ((nhanh thang) OR (nhanh thanh)) va dung cong van tuan ban*.
