• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (((te sach) OR (toc sach)))) ky lang xa hoi. hieu ve cham cuu ban anh ve cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (((te sach) OR (toc sach)))) ky lang xa hoi. hieu ve cham cuu ban anh ve cua tre*.
