Elastic search: how to write scripts of several operators?

Question

I have values ​​stored in a document in an Elasticsearch index.
I need to do some date manipulation for the values ​​and return the boolean value that will be used in the filter.
The script spans multiple lines, and I cannot get it to work.

I have written other single scripts that work just fine, however I know less than nothing about Groovy and very little about finding Elastic.

Each sample that I can find with the script has one line and only one line.

So basically, how would I take this perfectly valid script

"script": {
    "script": "doc['state'].value == 'completed' && doc['lastStateUpdate'].value < doc['dueDate'].value"
    }

And turn it into something like

"script": {
    "script": "def isCompleted = doc['state'].value == 'completed' 
               def preSLA = doc['lastStateUpdate'].value < doc['dueDate'].value
               return isCompleted && preSLA"
    }
