• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ky nang x hoi. hieu ((van cam) OR (van dau)) xuc ban thanh hai chau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) ky nang x hoi. hieu ((van cam) or (van dau)) xuc ban thanh hai chau tre".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (vu sach)) ky nang x hoi. hieu ((van cam) or (van dau)) xuc ban thanh hai chau tre*.
