I can't figure out how to re-index select fields using the Nest client for Elasticsearch. Basically, I want to do this:

> ```
> POST _reindex
> {
> "source": {
> "index": "twitter",
> "_source": ["user", "_doc"]
> },
> "dest": {
> "index": "new_twitter"
> }
> }
> 
> ```

and can't figure out what the Nest syntax is to specify the \_source fields.

It looks like it's missing from `ReindexOnServer(...)` on the high level client. [I've opened an issue to add it.](https://github.com/elastic/elasticsearch-net/issues/3288)

In the meantime, you can submit the request using the lowlevel client exposed on the high level, and still get back a high level response

```auto
var reindexResponse = client.LowLevel.Reindex<ReindexOnServerResponse>(@"{
      ""source"": {
        ""index"": ""twitter"",
        ""_source"": [""user"", ""_doc""]
      },
      ""dest"": {
        ""index"": ""new_twitter""
      }
    }");

```

Thank you. This is perfect.
