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