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