• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc sach y ((nang xa) OR (nang x)) hoi. hieu ((ve cau) OR (ke cau)) phuc va hanh de cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc sach y ((nang xa) OR (nang x)) hoi. hieu ((ve cau) or (ke cau)) phuc va hanh de cua tre".
