• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (thu sach)) ky nang xa hoi. hieu va cao xuc duy hanh ((vi cua) OR (vai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (thu sach)) ky nang xa hoi. hieu va cao xuc duy hanh ((vi cua) OR (vai cua)) triet".
