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