query in elasticsearch working thru postman but not thru java code

Question

I am trying to search a query in indian language among texts indexed in elasticsearch. When I fire a POST request thru postman, I get that record, but when I test it thru swagger, it's not working

Snapshot of postman

String url =  "http://localhost:9200/mono/_doc/_search?pretty";
        CloseableHttpClient httpClient = (HttpClients.createDefault());
        HttpPost httpPost = new HttpPost(url);
    httpPost.setHeader("content-type", "application/json");
System.out.println("Request : " + httpPost);

        httpPost.setEntity(entity);
        // Execute and get the response after ingesting PO (purchase order) into
        // Globality.
        HttpResponse response = httpClient.execute(httpPost);
        String response2 = EntityUtils.toString(response.getEntity());

        if (response2 != null) {
            System.out.println(response2);
        }

Debug output from code:

json2 is

 {"query":{"match":{"body":{"fuzziness":"2","query":"जन्मभूमि"}}}}

Request :

POST http://localhost:9200/mono/_doc/_search?pretty HTTP/1.1

Response:

{
  "took" : 1,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 0,
      "relation" : "eq"
    },
    "max_score" : null,
    "hits" : [ ]
  }
}

So as we see above, no result is returned. Is it because of HTTP version 1.0. Does it need to be 2.0?. if yes, how to specify it?. Is it something to do with indian language specific issue?. But not able to understand how its working thru postman but not thru java code.

One more thing, in postman it works with both GET and POST. In code, I wanted to first use GET, but didn't know how to send body with the GET request, so ended up using POST.

Working now. Added: StringEntity entity = new StringEntity(jsonString,"UTF-8"); — grit639
