• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sach - ((thanh trung) or (thanh tung)) cua ((truong dong) OR (tuong dong)) van toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((thanh trung) OR (thanh tung)) cua ((truong dong) OR (tuong dong)) van toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((thanh trung) or (thanh tung)) cua ((truong dong) OR (tuong dong)) van toan ban*".
