How to use template in elastic search

Elastic Stack Elasticsearch
1

Can I get syntax to implement template in elastic search ?

I have tried using following but no success

var templateRequest= new PutSearchTemplateDescriptor(new Id("my_template"));

templateRequest.Template("{"multi_match":{"query":{"query":"{{suggestion}}","fields":["field1","field2"]}}}");

var response = ElasticClient.PutSearchTemplate(templateRequest);

@Swapnil_Shah Hi,Could you please specify which client you are using and what version?

@Kallem_Prathyusha We are using the latest version of NEST .net client.We figured out putsearchtemplate is probably a wrong method to call. but not sure what is the right way to call a registered template from NEST client.Any examples would be immensely helpful
