• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky ((dang xa) OR (dang xay)) hoi. hieu van lam loc va thanh vi ((cua tu) OR (cua tuc))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky ((dang xa) or (dang xay)) hoi. hieu van lam loc va thanh vi ((cua tu) OR (cua tuc))*".
