Hi,  
I have field name with dot. like param.request\_id, this is actual field name and not

Actual:

```javascript
{
   "param.request_id": 12343
}

```

Not like

```javascript
{
 "param" : { 
   "request_id": 12343
  }
}

```

. when i try scripted filed

```java
if (doc.containsKey('param.request_id')) { 
    doc['param.request_id.keyword'].value 
}

```

However this code don't return any doc, instead it failed with script exception. is there a way to escape dot

Hi. Have you tried to access the field as suggested in [Fields with a "dot" in them do not persist](https://discuss.elastic.co/t/fields-with-a-dot-in-them-do-not-persist/234965/2) ?

Thanks for the reference, i still have error due to this field is not available in all documents, basically i have query param extracted out as `param.request_id` or in other case i have `param.input_id`  
in my product they all mean the same thing so i want to point to product page link reference this unique id, and in kibana table i want to refer it as one derived field.
