I have several indices where I save products:

```
product-example1
product-example2
product-example3
product-example4 
product-example5

```

I have the a document in elastic search that has the same structure and it can used for different indices:

```
@Data
@org.springframework.data.elasticsearch.annotations.Document(indexName = "", type = "", createIndex = false)
public class ProductDocument {

@Id
private String id;
private String title;
private String seller;
private String releaseDate;
....
}

```

So basically I want to use same settings, same mappings same search service.  
So I made `indexName` and `type` parametric in spring boot java, instead of creating 5 classes extending `ProductDocument` ?

```
@Autowired
private final ElasticsearchTemplate elasticsearchTemplate;	

this.elasticsearchTemplate.createIndex("product-example1", loadFile("/files/settings.json"));
this.elasticsearchTemplate.putMapping("product-example1", "product-type1", loadFile("/files/mapping.json"));

this.elasticsearchTemplate.createIndex("product-example2", loadFile("/files/settings.json"));
this.elasticsearchTemplate.putMapping("product-example2", "product-type2", loadFile("/files/mapping.json"));   

......

```

Now I want to create a ProductRepository but I don't have a class with defined index name. If I use generic class:

```
> public interface DocumentRepository extends ElasticsearchRepository<ProductDocument, String> {
> }

```

I get the error which is totally understable cause I created the index names in dynamic way:  
`lang.IllegalArgumentException: Unknown indexName. Make sure the indexName is defined. e.g @ProductDocument(indexName="foo")`

So is it possible somehow to create repository for indexs created in dynamic way and pass the index name and type as parameter ?
