(Optional, string) Comma-separated list or wildcard expression of index names used to limit the request. To retrieve statistics for all indices, use a value of _all or * or omit this parameter. Index Aliases edit APIs in Elasticsearch accept an index name when working against a specific index, and several indices when applicable. The index aliases API allows aliasing an index with a name, with all APIs automatically converting the alias name to the actual index name.
