• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y lang) OR (_ lang)) van hoa. thien van cau xuc ban ((hang vi) OR (hanh vi)) va triet.
• Adding a wildcard symbol may retrieve word variants: tu sach ((y lang) or (_ lang)) van hoa. thien van cau xuc ban ((hang vi) or (hanh vi)) va triet*.
