I am migrating from org.elasticsearch.\* to co.elastic.\* classes using elasticsearch-java dependency 8.10.2.  
It's really not obvious which co.elastic.\* classes are the org.elasticsearvh.\* equivalent when replacing the RestHighLevelClient with the new Java Api Client (low-level).  
In the past I used

```auto
MultiSearchResponse multiSearchResponse =
        elasticsearchClient.execute(MultiSearchAction.INSTANCE, multiSearchRequest).actionGet();

```

and afterwards I coould handle the SearchResponse.  
How do I have to refactor it using the ElasticsearchClient?  
From

```auto
MsearchResponse<Article> multiSearchResponse =
            elasticsearchClient.msearch(multiSearchRequest, Article.class);

```

I am not able anymore to get SearchResponse objects from. instead, I can get a MultiSearchItem by:  
`MultiSearchItem msi = multiSearchResponse.responses().get(0).result();` (Simplified access.)  
...but I am not able anymore to get a `SearchResponse` object to work upon although a `SearchResponse` class exists in co.elastic.\*  
This all is confusing.
