## Parameters

### Path parameters
- **index** (string | array[string])
  Comma-separated list of data streams, indices, and index aliases used to limit the request.
  Wildcard expressions (*) are supported.

### Query parameters
- **allow_no_indices** (boolean)
  A setting that does two separate checks on the index expression.
  If `false`, the request returns an error (1) if any wildcard expression
  (including `_all` and `*`) resolves to zero matching indices or (2) if the
  complete set of resolved indices, aliases or data streams is empty after all
  expressions are evaluated. If `true`, index expressions that resolve to no
  indices are allowed and the request returns an empty result.
- **expand_wildcards** (string | array[string])
  Type of index that wildcard expressions can match. If the request can target data streams, this argument
  determines whether wildcard expressions match hidden data streams. Supports comma-separated values,
  such as open,hidden.

  Supported values include:
    - `all`: Match any data stream or index, including hidden ones.
    - `open`: Match open, non-hidden indices. Also matches any non-hidden data stream.
    - `closed`: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
    - `hidden`: Match hidden data streams and hidden indices. Must be combined with `open`, `closed`, or `both`.
    - `none`: Wildcard expressions are not accepted.

- **flat_settings** (boolean)
  If true, returns settings in flat format.
- **ignore_unavailable** (boolean)
  If `false`, the request returns an error if it targets a concrete (non-wildcarded)
  index, alias, or data stream that is missing, closed, or otherwise unavailable.
  If `true`, unavailable concrete targets are silently ignored.
- **include_defaults** (boolean)
  If true, return all default settings in the response.
- **local** (boolean)
  If true, the request retrieves information from the local node only. Defaults to false, which means information is retrieved from the master node.
- **master_timeout** (string)
  Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.
- **features** (string | array[string])
  Return only information on specified index features

  Supported values include: `aliases`, `mappings`, `settings`
