• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ky nang xa hoi. hieu van ((cac xuc) OR (cam xuc)) va thanh hai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) ky nang xa hoi. hieu van ((cac xuc) or (cam xuc)) va thanh hai cua tre*".
