Hi, I try to make a scripted fields with size of message field value. I tried

```auto
doc['message'].value.getSize() 
doc['message'].value.size()

```

I tried also with `['message.keyword'] ` but nothing. I have in preview. Where am I wrong?  
Thank you

Hi @EugeneZ,

I tried with a sample data and it works with `length`: `doc['category.keyword'].value.length()`

Let me know if that fixed your problem!

Hmm...  
I try `return doc['message.keyword'].value.length()` and in preview I have

```auto
[
 {
  "_id": "R7h8RXUBp5UPtyZb69B4",
  "sf_msg_size": [
   63
  ]
 },
 {
  "_id": "SLh8RXUBp5UPtyZb69B4",
  "sf_msg_size": [
   63
  ]
 },

```

It is somethig but not 'message' length.

What's the expected outcome then? For me it works perfectly, eg. for the example I gave, it returns

```auto
[
 {
  "_id": "WmrTl3UB9Atbtm2uF-nb",
  "scripted_len": [
   13
  ]
 }...
 ]

```

And my first result is `Women's Clothing` which is 13 characters long.
