• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach ky) OR (sac ky))) OR (sach y)) van tay hoi. hieu van hac nuoc va thanh vai cac tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach ky) OR (sac ky))) or (sach y)) van tay hoi. hieu van hac nuoc va thanh vai cac tren~".
• Adding a wildcard symbol may retrieve word variants: te ((((sach ky) OR (sac ky))) or (sach y)) van tay hoi. hieu van hac nuoc va thanh vai cac tren*.
