• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((hieu lang) OR (chieu sach)) - hanh truong cua thong ((thong ban) OR (thong van)) than cau~.
• Adding a wildcard symbol may retrieve word variants: doi ((hieu lang) or (chieu sach)) - hanh truong cua thong ((thong ban) or (thong van)) than cau*.
