• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (co sach)) ty nang xa hoi. hieu ve cac xuc va ((danh vi) OR (hanh vi)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) OR (co sach)) ty nang xa hoi. hieu ve cac xuc va ((danh vi) or (hanh vi)) cua te".
