Hello,

I am using RestHighLevelClient  
(elasticsearch-rest-high-level-client-7.17.16.jar)

and I get a warning from our 7.17.13 server

> Warning: 299 Elasticsearch-7.17.13-2b211dbb8bfdecaf7f5b44d356bdfe54b1050c13 "Deprecated field [type] used, this field is unused and will be removed entirely"

This is filling up my stack logs. Is there a way to get rid off this warning.  
What are my options ?  
I guess using

> **[Elasticsearch Java API Client \[7.17\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/7.17/index.html)**

will solve the issue ?  
Thank you

The log message says "this field is unused and will be removed entirely". So your best option is most certainly to stop using this `type` field!

Hello,  
the "type" field it is complaining about, is the one from the GeoBoundingBoxQueryBuilder 7.17.16 class.

[https://javadoc.io/doc/org.elasticsearch/elasticsearch/7.17.16/org/elasticsearch/index/query/GeoBoundingBoxQueryBuilder.html](https://javadoc.io/doc/org.elasticsearch/elasticsearch/7.17.16/org/elasticsearch/index/query/GeoBoundingBoxQueryBuilder.html)

```auto
{
  "geo_bounding_box" : {
    "location" : {
      "top_left" : [
        -0.5,
        45.0
      ],
      "bottom_right" : [
        0.5,
        44.2
      ]
    },
    "validation_method" : "STRICT",
    "type" : "MEMORY",
    "ignore_unmapped" : true,
    "boost" : 1.0
  }
}

```

Here is some code that reproduce the issue:

```auto
public class MyMain {
    public static void main(String arg[]) {
        final CredentialsProvider credentialProvider = new BasicCredentialsProvider();
        credentialProvider.setCredentials(
                AuthScope.ANY,
                new UsernamePasswordCredentials(
                        "my un",
                        "my_pw"
                ));

        RestHighLevelClient highLevelClient = new RestHighLevelClient(
                RestClient.builder(new HttpHost("my_server_address", 9200, "http"))
                        .setHttpClientConfigCallback(httpAsyncClientBuilder -> {
                            httpAsyncClientBuilder.setDefaultCredentialsProvider(credentialProvider);
                            return httpAsyncClientBuilder;
                        })
        );

        // Calling API synchronously.
        try {
            CountRequest request = new CountRequest(new String[]{"pj-search-request-alias-1-dev"});

            SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();

            final GeoBoundingBoxQueryBuilder geoBuilder = QueryBuilders
                    .geoBoundingBoxQuery("location")
                    .setCorners(45.0, -0.5, 44.2, 0.5)
                    .ignoreUnmapped(true);

            QueryBuilder queryBuilder = QueryBuilders
                    .boolQuery()
                    .should(geoBuilder);

            searchSourceBuilder.query(queryBuilder);
            request.source(searchSourceBuilder);

            CountResponse count = highLevelClient.count(request, RequestOptions.DEFAULT);
            System.out.println(" ******* done" + count);

        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
}

```

Thanks for the additional details. By default the `RestHighLevelClient` will send `type = "MEMORY"` and the server will issue a warning. And unfortunately setting `type` to `null` will throw an exception.

There are two options:

- use the Java API client for this request. You don't have to migrate your entire application: Java API client and HLRC can [smoothly work side by side with the same low level client](https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/7.17/migrate-hlrc.html).
- disable [deprecation warnings on the server](https://discuss.elastic.co/t/turn-off-es-deprecation-logs-dynamically/221948). But this will hide all deprecation warnings, which may be valuable information.

OK, thanks for the reply, will disable warnings through config for now.
