• If you are trying to use Boolean operators, they must be ALL CAPS: ((((toc sach) OR (doc sach))) OR (thuat sach)) tay lang ha hoi. hieu ve cham tu van anh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((toc sach) OR (doc sach))) or (thuat sach)) tay lang ha hoi. hieu ve cham tu van anh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: ((((toc sach) OR (doc sach))) or (thuat sach)) tay lang ha hoi. hieu ve cham tu van anh vi cua te*.
