The [docs](https://www.elastic.co/guide/en/elasticsearch/client/net-api/7.17/unrecoverable-exceptions.html) say:

> By default, the client won’t throw on any `ElasticsearchClientException` but instead return an invalid response that can be detected by checking the `.IsValid` property on the response. You can change this behaviour with by using `ThrowExceptions()` on [`ConnectionSettings`](https://www.elastic.co/guide/en/elasticsearch/client/net-api/7.17/configuration-options.html).

How to interpret this? I'd think that enabling `ThrowExceptions()` on the connection should always throw an exception when `IsValid` would be `false`. However, I noticed that this call: `await _client.BulkAsync(descriptor, cancellationToken);` does not throw even if it does not succeed (e.g. due to missing index in elasticsearch). The response has `IsValid` equal to `false`

What is the actual relationship between `IsValid` and the `ThrowExceptions()` setting?
