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