• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ((kho lang) OR (cho lang)) xa hoi. hieu va nam xuc van hanh dan cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) ((kho lang) OR (cho lang)) xa hoi. hieu va nam xuc van hanh dan cua triet".
