Your search query in Postman is not the same as your search query in NEST.

In Postman

GET http://localhost:9200/bankpayoutsummary/data/_search?q=taluka=Pauni

is a query_string query, equivalent to

client.Search<Bankpayoutsummary>(s => s
	.Index("bankpayoutsummary")
	.Type("data")
	.Query(q => q
		.QueryString(qs => qs
			.Query("taluka=Pauni")
		)
	)
);

with NEST. This would generate the following query

POST http://localhost:9200/bankpayoutsummary/data/_search
{
  "query": {
    "query_string": {
      "query": "taluka=Pauni"
    }
  }
}

I also think you might want taluka:Pauni for your query, with the supported syntax
