• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty danh xay hoi. hieu ((ve cam) OR (va cam)) xuc ((ban anh) OR (ban hanh)) hai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty danh xay hoi. hieu ((ve cam) or (va cam)) xuc ((ban anh) OR (ban hanh)) hai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty danh xay hoi. hieu ((ve cam) or (va cam)) xuc ((ban anh) OR (ban hanh)) hai cua tre*.
