• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - ((nhanh tinh) OR (hanh trinh)) va thong cong tap ((toan cao) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - ((nhanh tinh) OR (hanh trinh)) va thong cong tap ((toan cao) or (toan tap))*".
