Hi All,

I am using ELK 8.0.0 version and wanted to know can we merge or join the 2 different document ID into a single data with a common field value in both the documents.

e.g  
first document ID has below data  
emp\_name : gaurav  
emp\_sex: male  
emp\_id : 22

and

second document has below data  
emp\_location : leads  
emp\_id : 22

so after the merge or join we should get a below data in a single document  
emp\_name : gaurav  
emp\_sex: male  
emp\_location : leads  
emp\_id : 22

Please suggest if we have any such features or processor we can use or any scripting, Any help/suggestion will be appreciated.

That is exactly the purpose of the [enrich processor](https://www.elastic.co/guide/en/elasticsearch/reference/current/enrich-processor.html). Take a look at this complete guide on how to enrich documents with values from a reference index
