• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (chieu tinh)) - ((anh sang) OR (anh dong)) va duong cong dan van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) OR (chieu tinh)) - ((anh sang) or (anh dong)) va duong cong dan van ban".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) OR (chieu tinh)) - ((anh sang) or (anh dong)) va duong cong dan van ban*.
