Get the indices and shards that a search request would be run against.
This information can be useful for working out issues or planning optimizations with routing and shard preferences.
When filtered aliases are used, the filter is returned as part of the `indices` section.

If the Elasticsearch security features are enabled, you must have the `view_index_metadata` or `manage` index privilege for the target data stream, index, or alias.

## Required authorization

* Index privileges: `view_index_metadata`

## Parameters

### Path parameters
- **index** (string | array[string])
  A comma-separated list of data streams, indices, and aliases to search.
  It supports wildcards (`*`).
  To search all data streams and indices, omit this parameter or use `*` or `_all`.

### 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 patterns 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.

- **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.
- **local** (boolean)
  If `true`, the request retrieves information from the local node only.
- **master_timeout** (string)
  The period to wait for a connection to the master node.
  If the master node is not available before the timeout expires, the request fails and returns an error.
  IT can also be set to `-1` to indicate that the request should never timeout.
- **preference** (string)
  The node or shard the operation should be performed on.
  It is random by default.
- **routing** (string | array[string])
  A custom value used to route operations to a specific shard.
