• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. hieu van chat xuc va ((dan vi) OR (((doan vi) OR (don vi)))) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. hieu van chat xuc va ((dan vi) or (((doan vi) OR (don vi)))) cua tre".
