• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - thanh tung phap thong ((((trung dan) OR (trung dai))) OR (tung dan)) van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh tung phap thong ((((trung dan) OR (trung dai))) or (tung dan)) van ban*".
