• If you are trying to use Boolean operators, they must be ALL CAPS: so canh may nang ((x hoi) OR (xa hoi)). hieu ((ve pham) OR (ve phan)) thuc day hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so canh may nang ((x hoi) OR (xa hoi)). hieu ((ve pham) or (ve phan)) thuc day hanh vai cua tre*".
