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