In the docs it has this example ([Aliases API | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-aliases.html#aliases-write-index))

```auto
POST /_aliases
{
    "actions" : [
        {
            "add" : {
                 "index" : "test",
                 "alias" : "alias1",
                 "is_write_index" : true
            }
        }
    ]
}

```

and then says about the example

> In this example, we associate the alias `alias1` to both `test` and `test2` , where `test` will be the index chosen for writing to.

Where does the `test2` index come from?

This is an error IMO. This text should be placed later in this section where test2 is also defined.  
Would you like to open an issue or better a PR?
