I am trying to append a nested field value using java api.  
Here is my doc structure:

```
{
"Name" : "ABC",
"Tag" : { [
"Tag1" : "DEF"
]}
}    

```

How do I append another Tag1 value so that final doc looks like this:

```
{
"Name" : "ABC",
"Tag" : { [
"Tag1" : "DEF",
"Tag1" : "GHI"
]}
}   

```

Following is the script that I use:

```
UpdateRequest updateRequest = new UpdateRequest("test", "testing", "1")
    		        .script(new Script("ctx._source.Tag.Tag1 += "+ TagValue ));
    		client.update(updateRequest).get();

```

What is the correct way to access and append new Tag1 values?
