• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty lang ha hoi. hieu va cham luc ((van anh) OR (van minh)) tri ((cua te) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty lang ha hoi. hieu va cham luc ((van anh) or (van minh)) tri ((cua te) OR (cua tu))*".
