• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thuat sach)) ky ((nang xa) OR (nang x)) hoi. thieu nien cac tuc va hanh than cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thuat sach)) ky ((nang xa) OR (nang x)) hoi. thieu nien cac tuc va hanh than cua te~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thuat sach)) ky ((nang xa) OR (nang x)) hoi. thieu nien cac tuc va hanh than cua te*.
