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