• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chuc danh) OR (chieu xanh)) - hanh tang van ((nhung cong) OR (thong cong)) van toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chuc danh) or (chieu xanh)) - hanh tang van ((nhung cong) OR (thong cong)) van toan ban".
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chieu xanh)) - hanh tang van ((nhung cong) OR (thong cong)) van toan ban*.
