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