I'm trying to do full text query search on if i GET http://localhost:8080/search/query/tes it should show users include tes in first or last name. i implemented them. but something is wrong, it says hits not found (JSONObject["hits"] not found). Spring Boot with Elasticsearch

private static final Logger LOGGER = LoggerFactory.getLogger(SearchService.class);
@Override
public ResultQuery searchFromQuery(String query) throws IOException {
String body = HelperFunctions.buildMultiIndexMatchBody(query);
return executeHttpRequest(body);
}
/**

try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
ResultQuery resultQuery = new ResultQuery();
HttpPost httpPost = new HttpPost(HelperFunctions.buildSearchUri(elasticSearchUri
, "", elasticSearchSearchPrefix));
httpPost.setHeader(Accept, application/json);
httpPost.setHeader(Content-type, application/json);
try {
httpPost.setEntity(new StringEntity(body, UTF-8));
HttpResponse response = httpClient.execute(httpPost);
String message = EntityUtils.toString(response.getEntity());
JSONObject myObject = new JSONObject(message);
if(myObject.getJSONObject(hits)
.getInt(total) != 0){
resultQuery
.setElements(myObject
.getJSONObject(hits)
.getJSONArray(hits)
.toString());
resultQuery
.setNumberOfResults(myObject.getJSONObject(hits)
.getInt(total));
resultQuery.setTimeTook((float) ((double) myObject.getInt(took) / 1000));
} else {
resultQuery.setElements(null);
resultQuery.setNumberOfResults(0);
resultQuery.setTimeTook((float) ((double) myObject.getInt(took) / 1000));
}
} catch (IOException | JSONException e) {
LOGGER.error("Error while connecting to elastic engine --> {}", e.getMessage());
resultQuery.setNumberOfResults(0);
}return resultQuery;}
