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