• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((dang xa) OR (van xay)) hoi. hieu van cham cuu ban hanh ((vi cua) OR (vai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((dang xa) or (van xay)) hoi. hieu van cham cuu ban hanh ((vi cua) OR (vai cua)) tre*".
