• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ky nang xa hoi. thi ((van bac) OR (van hac)) ((xuc van) OR (luc van)) hanh thai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ky nang xa hoi. thi ((van bac) OR (van hac)) ((xuc van) or (luc van)) hanh thai cua tre".
