• If you are trying to use Boolean operators, they must be ALL CAPS: te sach van nang xa hoi. ((hieu van) OR (thien van)) hat luu hinh ((anh le) OR (oanh le)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach van nang xa hoi. ((hieu van) or (thien van)) hat luu hinh ((anh le) OR (oanh le)) cua tre".
