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