• If you are trying to use Boolean operators, they must be ALL CAPS: doi trieu tinh - hanh tinh cua ((((nhung cong) OR (hang cong))) OR (dang cong)) manh toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi trieu tinh - hanh tinh cua ((((nhung cong) OR (hang cong))) or (dang cong)) manh toan cao*".
