 | `allow_no_indices` | Boolean | If `false`, the request returns an error if any wildcard expression or index alias targets any closed or missing indexes. Default is `true`. |
-| `expand_wildcards` | Specifies the types of indexes to which wildcard expressions can expand. Supports comma-separated values. Valid values are: <br> - `all`: Expand to all open and closed indexes, including hidden indexes. <br> - `open`: Expand to open indexes. <br> - `closed`: Expand to closed indexes. <br> - `hidden`: Include hidden indexes when expanding. Must be combined with `open`, `closed`, or both. <br> - `none`: Do not accept wildcard expressions. <br> Default is `open`. |
