• If you are trying to use Boolean operators, they must be ALL CAPS: ((((su sach) OR (so sach))) OR (so sanh)) v nang xa hoi. hieu van bac thuc va danh du cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((su sach) OR (so sach))) or (so sanh)) v nang xa hoi. hieu van bac thuc va danh du cua tre*".
