• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ky nang xa hoi. lieu va bac luc va ((hanh lam) OR (hanh kem)) chat triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) ky nang xa hoi. lieu va bac luc va ((hanh lam) OR (hanh kem)) chat triet".
