Path parameters

  • index string | array[string] Required

    Comma-separated list of data streams, indices, and aliases. Supports wildcards (*).

Query parameters

  • allow_no_indices boolean

  • 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. Valid values are: all, open, closed, hidden, none.

  • flat_settings boolean

    If true, returns settings in flat format.

  • ignore_unavailable boolean

    If false, the request returns an error if it targets a missing or closed index.

  • 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.
