• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chiet tach)) - thanh tinh ((chat nhung) OR (cua nhung)) cong van toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chiet tach)) - thanh tinh ((chat nhung) OR (cua nhung)) cong van toan tap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (chiet tach)) - thanh tinh ((chat nhung) OR (cua nhung)) cong van toan tap*.
