• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) v nang xa hoi. hieu ve cam luc va ((hanh cua) OR (hang cua)) cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) v nang xa hoi. hieu ve cam luc va ((hanh cua) or (hang cua)) cua viet".
