• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh manh cua ((((nhung cong) OR (hang cong))) OR (thong cong)) van phan tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh manh cua ((((nhung cong) OR (hang cong))) or (thong cong)) van phan tu*".
