• If you are trying to use Boolean operators, they must be ALL CAPS: o chau tinh - ((hanh trinh) OR (canh tranh)) cua nhung cong ((dan chan) OR (ban than)) cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "o chau tinh - ((hanh trinh) OR (canh tranh)) cua nhung cong ((dan chan) or (ban than)) cap*".
