Hi,

In v.7.X the search performed as follow:

```auto
searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);

```

How do I perform search in v.8 without defining the target class for the matching documents. (I want to keep it as json without searlization, without specifying Product class)

```auto
searchResponse = client.search(searchRequest, Product.class);

```

I think you can use `Void.class`.  
And do something like this to get the JSON Response:

I tried:

```auto
searchResponse = client.search(searchRequest, Void.class);

```

Failed with:

```auto
The method search(SearchRequest, Class<TDocument>) in the type ElasticsearchClient is not applicable for the arguments (SearchRequest, Class<Void>)	

```

I'm not sure why `Void.class` does not work here, but for your purpose I would try to have the response read as raw json, using for instance `ObjectNode.class` as in
