• If you are trying to use Boolean operators, they must be ALL CAPS: su bac ky nang x hoi. hieu ((qua chat) OR (luan phan)) ((xuc van) OR (vuc van)) thanh va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su bac ky nang x hoi. hieu ((qua chat) or (luan phan)) ((xuc van) OR (vuc van)) thanh va cua tre*".
