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