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