• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu sach)) - hanh han cua dung song van ((than cao) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chieu sach)) - hanh han cua dung song van ((than cao) OR (toan cao))*".
