Hi xavier,

My elasticsearchconfiguration:

```
@Configuration
@PropertySource(value = "classpath:application.properties")
@EnableElasticsearchRepositories(basePackages = "com.backend.project.repositories")
public class ElasticsearchConfiguration {

@Bean
public Client client() throws Exception{
    TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
    .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("elasticsearch.host"), 9200));    
    return client;
}
    @Bean
    public ElasticsearchOperations elasticsearchTemplate() throws Exception {
    return new ElasticsearchTemplate(client());
     }
}

```

My webapplication:

```
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan(basePackages = "com.backend.project")
@EnableAutoConfiguration
@SpringBootApplication
public class WebApplication {
    public static void main(String args[]){
        SpringApplication.run(WebApplication.class);
    }
}

```

My Post.java:

```
@Document(indexName = "post", type = "post", shards = 1, replicas = 0)
public class Post {
@Id
private String id; private String title;// 
@Field(type= FieldType.Nested)
private List<Tag> tags;   
 public String getId() {
        return id;
}
    public void setId(String id) {
        this.id = id;
}
    public String getTitle() {
        return title;
}
    public void setTitle(String title) {
        this.title = title;
}
    public List<Tag> getTags() {
        return tags;
}
    public void setTags(List<Tag> tags) {
        this.tags = tags;}
}

```

My Tag.java:

```
public class Tag {
 private String id;   
 private String name;   
 public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
  }
}

```

My PostRepository:

```
public interface PostRepository extends ElasticsearchRepository<Post, String>{
 
    Page<Post> findByTagsName(String name, Pageable pageable);
}

```

My PostService:

```
public interface PostService {
    Post save(Post post);
    Post findOne(String id);
    Iterable<Post> findAll();
    Page<Post> findByTagsName(String tagName, PageRequest pageRequest);
}

```

My PostServiceImpl:

```
@Service
public class PostServiceImpl implements PostService{
        @Autowired
    private PostRepository postRepository;
    @Override
    public Post save(Post post) {
            postRepository.save(post);      
              return post;
       }
    @Override
    public Post findOne(String id) {
        return postRepository.findOne(id);
   }
    @Override
    public Iterable<Post> findAll() {
        return postRepository.findAll();
   }
    @Override
    public Page<Post> findByTagsName(String tagName, PageRequest pageRequest) {
        return postRepository.findByTagsName(tagName, pageRequest);
   }
}
```

AFAIK Spring data project has not been updated for elasticsearch 5.x. Just a guess though as I did not check recently.

Check if you have the same version in your java project than your ES instance.

Just a question, the port should not be 9300 ?

```
.addTransportAddress(
            new InetSocketTransportAddress(
                     InetAddress.getByName("elasticsearch.host"), 
                     9200));
```

This is not the version of the software. What is the Elasticsearch version you have install as a service ?

try:

```
curl -XGET 'http://localhost:9200/_nodes/_all/version?pretty='

```

Exemple:

```
  "version" : "2.4.4",
```

Ok, this is not possible, you must have your cluster AND your clients with the major same version.

Read:  
[https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/client.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/client.html)

```
The client must have the same major version (e.g. 2.x, or 5.x) as the nodes in the cluster. Clients 
may connect to clusters which have a different minor version (e.g. 2.3.x) but it is possible that 
new functionality may not be supported. Ideally, the client should have the same version as the cluster.

It means that your java client (depencies) must be the same than your server.

Your ES is 5.x.x so you have to set the same major version in your java dependencies.

@Read: [https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/index.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/index.html)

```
<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>transport</artifactId>
    <version>5.3.0</version>
</dependency>

```

Else you have to downgrade your ES server to 4.x.x if you can change your Java dependencies.
