• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((hanh trang) OR (hanh trinh)) cua nhung ((cong van) OR (song van)) tuan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((hanh trang) OR (hanh trinh)) cua nhung ((cong van) or (song van)) tuan cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((hanh trang) OR (hanh trinh)) cua nhung ((cong van) or (song van)) tuan cao*.
