Hi,  
Since nested array is not well supported in Kibana, is there any way I could extract the value from the array using scripted field?

My data looks like this  
1st document:

"page\_name": [  
{  
"name": "New York"  
},  
{  
"url": "[https://newyork.com](https://newyork.com)"  
},  
]

2nd document:

"page\_name": [  
{  
"name": "Berlin"  
},  
{  
"url": "[https://berlin.de](https://berlin.de)"  
},  
]

It'd be great if I could use the Tag Cloud and visualize **page\_name.name**  
However, it seems not yet supported, so I figured may be I should use scripted field.

What is the script that allows me to access my field **page\_name.name**?

`page_name.name` should work as a path for the string. Have you tried it and it's not working?

I used

if(doc['page\_name.name.keyword']!= null)doc['page\_name.name.keyword']

and it still returns nothing, how can I access an index 0 of an array in painless?
