• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh doanh) OR (hang doanh)) cua nhung ((cong thanh) or (cong san)) van ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh doanh) OR (hang doanh)) cua nhung ((cong thanh) or (cong san)) van ban*.
