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