• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (su sach)) ky nang cao hoi. hieu ve cham xuc va danh sai ((va triet) OR (va thiet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (su sach)) ky nang cao hoi. hieu ve cham xuc va danh sai ((va triet) OR (va thiet))".
