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