• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) thi nang xa hoi. hieu van ((cham xuc) OR (chat xuc)) ban thanh hai ca viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) thi nang xa hoi. hieu van ((cham xuc) OR (chat xuc)) ban thanh hai ca viet".
