jSON query in NEST 5.0

Elastic Stack Elasticsearch
1

In debugger i was able to look at the jSON query that is being sent to Elasticsearch in version 1.7.
After upgrading to v5.0, i cannot find the jSON query that is being sent to Elasticsearch.

You can see the json sent to and received from Elasticsearch by setting a few options on ConnectionSettings:

var pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));

var connectionSettings = new ConnectionSettings(pool)
        // pretty print all requests and responses to Elasticsearch
        .PrettyJson()
        // buffer the request and response bytes in MemoryStream
        .DisableDirectStreaming()
        // a delegate to run when a request completes. Use this to capture 
        // request and response information
        .OnRequestCompleted(response =>
            {
                // log out the request
                if (response.RequestBodyInBytes != null)
                {
                    Console.WriteLine(
                        $"{response.HttpMethod} {response.Uri} \n" +
                        $"{Encoding.UTF8.GetString(response.RequestBodyInBytes)}");
                }
                else
                {
                    Console.WriteLine($"{response.HttpMethod} {response.Uri}");
                }

                Console.WriteLine();

                // log out the response
                if (response.ResponseBodyInBytes != null)
                {
                    Console.WriteLine($"Status: {response.HttpStatusCode}\n" +
                             $"{Encoding.UTF8.GetString(response.ResponseBodyInBytes)}\n" +
                             $"{new string('-', 30)}\n");
                }
                else
                {
                    Console.WriteLine($"Status: {response.HttpStatusCode}\n" +
                             $"{new string('-', 30)}\n");
                }
            });

var client = new ElasticClient(connectionSettings);

Now with this in place, we can capture the request and responses. .DisableDirectStreaming() can also be set on a per-request basis so that request and response bytes are only buffered when necessary, as doing so will have an impact on performance.
