How to do an ElasticSearch using REST request body method and get the returned json formatted / pretty? - elasticsearch

Question

In issuing a search request, via REST Request Body method, such as
GET /bank/_search
{
"query": { "match_all": {} },
"sort": [
{ "account_number": "asc" }
]
}
is there a parameter that can be added anywhere to request the returned response body's json be formatted/pretty ?
The same search using REST Request URI enables to do that, like
GET /bank/_search?q=*&sort=account_number:asc&pretty
How to achieve the same using REST request body ?
Using ElasticSearch.NET's low level api, one have no control over the REST call, and can only provide the POST json.
var esClient = new ElasticLowLevelClient(_connectionSettings);
//postDataJson is the json depicted in the question's body
var postData = PostData.String(postDataJson);
var response = esClient.Search<StringResponse>("myIndex", postData);
One can send a third parameter, a SearchRequestParameters object, I can't find any property there for that.

Answer 1

You need to add to your request pretty=true
Like that:
GET /bank/_search?q=*&sort=account_number:asc&pretty=true

EDIT
I didn't understand you at first, the pretty should be in the header of the request.
Try like that:
GET /bank/_search?pretty=true
{
"query": { "match_all": {} },
"sort": [
{ "account_number": "asc" }
]
}
EDIT 2
If you are using elstic.NET and you want too achieve pretty Jason.
You need to configure it in the connection.
Here is the method you should use(it's in the classConnectionConfiguration : ConnectionConfiguration<ConnectionConfiguration>):
/// <summary>
/// Forces all requests to have ?pretty=true querystring parameter appended,
/// causing Elasticsearch to return formatted JSON.
/// Also forces the client to send out formatted JSON. Defaults to <c>false</c>
/// </summary>
public T PrettyJson(bool b = true) => Assign(a =>
{
this._prettyJson = b;
const string key = "pretty";
if (!b && this._queryString[key] != null) this._queryString.Remove(key);
else if (b && this._queryString[key] == null)
this.GlobalQueryStringParameters(new NameValueCollection { { key, "true" } });
});
