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