Hi,

I am using the Elasticsearch API client (8.9) for java and wondering how to render those Queries and Responses as json strings.  
For example I can do a simple query like so:

```auto
val query = Query.of { q -> q.matchAll { it } }
val request = SearchRequest.of {
   it.query(query)
  it.index("some_index")
}
val response = esClient.search(request, Any::class.java)

val queryJson = query.toString() // this yields the json but there is "Query: " prepended
val responseJson = response.toString() // this yields the json but there is "SearchResponse: " prepended

val mapper = ObjectMapper()
mapper.setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY)
val string = mapper.writeValueAsString(result) // this works

```

Since the client can render the whole thing as json in the `toString` method the capability is there. There is just a type annotation prepended and I can't find a method to just render the whole thing as json.  
Jackson ObjectMapper can render it if I configure it to render fields and not look for getters, but this seems to be unecessarily complicated the the objects themselven _can_ render as json.  
So my question is, what is the best way to get all these things as Json strings with an onboard method or do I really have to rely on an external Json mapper?

Cheers and thanks!

Have a look at this class:

```
co.elastic.clients.json.JsonpUtils

```

There's a toJsonString() method.

Thanks again for the fast reply, it works like a charm. Yields the same results as objectMapper but I feel way more comfortable using an ES scoped class for this than a generic mapper!
