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