Consider the following document

```auto
{
  "title": "My first blog entry",
  "text": "Starting to get the hang of this...",
  "tags": ["testing"], 
  "views": 0 
}

```

I need to run kind of an upsert operation. If I encounter data like

```auto
{
    "id": 1,
    "tags": ["new tag"]
}

```

I want to update the existing document with same id. So result should be :

```auto
{
    "id": 1,
    "title": "My first blog entry",
    "text": "Starting to get the hang of this...",
    "tags": ["testing", "new tag"], 
    "views": 0 
}

```

If the document with same id does not exist, I want to create a new one.

In Solr I could do this using Atomic updates. Is there a way to do this in Elasticsearch using Bulk API in Java?
