I have been trying to use scripted fields to test for elements which exists inside a list, but after hours of trying different syntax + reading the documentations, I still can’t figure out how to do it properly. Here is a single document:

```

    ],
    "content_first_word": [
      "that"
    ]
  }
}

```

What I would like to grab is the [author.roles.name](http://author.roles.name) and test it against a list of names then return a name if there is a match. I have eventually got to:

```
def roles = doc["author.roles.name.keyword"].value 

```

but that returns the last element only which is not what I wanted.

I have tried:

```
def roles = doc["_source"]["author"]["roles"]

```

but that doesn’t seem to return it as a list either. Hopefully someone could help me out as I don’t even know if it is syntax error or what it is…

Thanks!

Hi there, I found this similar thread from awhile back: [Changing all array elements in scripted field](https://discuss.elastic.co/t/changing-all-array-elements-in-scripted-field/82246)

In that thread, the author uses the "values" property to retrieve all of the values in the array. So in your example, it would be:

```auto
def roles = doc["author.roles.name.keyword"].values

```

Can you try this and let me know if it works for you?

Thanks,  
CJ
