• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (su sach)) ky nang xa hoi. hieu van ((chat xuc) OR (chao xu)) ban banh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (su sach)) ky nang xa hoi. hieu van ((chat xuc) OR (chao xu)) ban banh di cua tre".
