• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - anh ban quan dung ((cong manh) OR (cong danh)) ((toan tap) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - anh ban quan dung ((cong manh) OR (cong danh)) ((toan tap) or (toan ban))*".
