• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang hoa hoi. hieu ly nam ((thuy van) OR (thuc van)) hanh ((vai su) OR (va su)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang hoa hoi. hieu ly nam ((thuy van) OR (thuc van)) hanh ((vai su) or (va su)) triet".
