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