• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ((ky sang) OR (ky dang)) xa hoi. hieu ve cam xuc ((va hanh) OR (va dan)) hoa cua tre.
• Adding a wildcard symbol may retrieve word variants: tu cac ((ky sang) or (ky dang)) xa hoi. hieu ve cam xuc ((va hanh) or (va dan)) hoa cua tre*.
