• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach tri tue danh co phan tong ) OR ( tu sach thue tu nganh khong phap phong ))~.
• Adding a wildcard symbol may retrieve word variants: (( tu sach tri tue danh co phan tong ) or ( tu sach thue tu nganh khong phap phong ))*.
