• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky ((nang xa) OR (nang x)) hoi. hieu ((dien sach) OR (vien bach)) tuoc va danh di cua tuc*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky ((nang xa) OR (nang x)) hoi. hieu ((dien sach) or (vien bach)) tuoc va danh di cua tuc*".
