• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach tu nang xa hoi. hieu vien cac xuc ((va thanh) OR (ban hanh)) vai ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach tu nang xa hoi. hieu vien cac xuc ((va thanh) or (ban hanh)) vai ((cuu tre) OR (cau treo))*".
