With ES8 java client to get index  
client.indices().get(c -\> c.index(name).features(...))

I didn't find the method corresponding to the following param:

**`features`**  
(Optional, string) Return information about specific index features. Supports comma- separated values. Valid values are `aliases` , `mappings` , and `settings` . Defaults to `aliases,mappings,settings` .

Ref: [Get index API | Elasticsearch Guide [8.2] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-get-index.html)

Maybe I miss sth? Please advice.

Thank you !

Hi!!  
I work this way:

```auto
    GetIndexResponse indices = client.indices().get(i -> i.index("idx_example"));
    IndexState indexState = indices.get("idx_example");
    IndexSettings settings = indexState.settings();
    TypeMapping mappings = indexState.mappings();
    Map<String, Alias> aliases = indexState.aliases();

```

Thank you! That works.  
Hope the API can provide sth corresponding to the REST. That will make the code cleaner.
