• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sang) OR (chinh sach)) - hanh trang cua nhung huong ((dan toan) OR (manh toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) or (chinh sach)) - hanh trang cua nhung huong ((dan toan) OR (manh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) or (chinh sach)) - hanh trang cua nhung huong ((dan toan) OR (manh toan)) cau*.
