• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((thanh trong) OR (tran trong)) van dang cong ((ban than) OR (ban hang)) cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((thanh trong) or (tran trong)) van dang cong ((ban than) OR (ban hang)) cap*".
