• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chinh sach) OR (chieu tinh)) - hinh trong tham nhung cong ((van van) OR (tan van)) ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chinh sach) or (chieu tinh)) - hinh trong tham nhung cong ((van van) OR (tan van)) ban".
• Adding a wildcard symbol may retrieve word variants: ho ((chinh sach) or (chieu tinh)) - hinh trong tham nhung cong ((van van) OR (tan van)) ban*.
