• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ky nang xa hoi. hieu va cau luc ((va danh) OR (ly doanh)) va ((su triet) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ky nang xa hoi. hieu va cau luc ((va danh) or (ly doanh)) va ((su triet) OR (ve triet))".
