Get final query from Elasticsearch Nest client

First you have to set this flag

var settings = new ConnectionSettings(connectionPool)
    .DisableDirectStreaming();

📓This is for Nest client 6.X: Debug Information in 6.x the default is true

/// <summary>
/// Ensures the response bytes are always available on the <see cref="T:Elasticsearch.Net.ElasticsearchResponse`1" /><para>
/// IMPORTANT: Depending on the registered serializer,
/// this may cause the response to be buffered in memory first, potentially affecting performance.
/// </para></summary>
public T DisableDirectStreaming(bool b = true) => this.Assign<bool>(b, (Action<ConnectionConfiguration<T>, bool>) ((a, v) => a._disableDirectStreaming = v));

But for the most current version 8.X this is a summary:

DisableDirectStreaming When set to true will disable (de)serializing directly to the request and response stream and return a byte[] copy of the raw request and response. Defaults to false.

If you have something like this:

var initialResponse = await _elasticClient.SearchAsync<TResult>
            (scr => scr
                .From(0)
                .Size(scrollSize)
                .Type(docTypeName)
                .Query(q => query)
                .Scroll(scrollTimeout));

in the immediate window (or similar tool) you can call this:

initialResponse.DebugInformation

Or

_elasticClient.RequestResponseSerializer.SerializeToString(query);
