Hello team,

I wrote a script to get month (string) = doc['@timstamp'].value.getMonth().  
Year=doc['@timstamp'].value.getYear().

Used concatenation montheYear=doc['@timstamp'].value.getMonth()+doc['@timstamp'].value.getYear().

Error: String + integer is not possible .

please help me to get year in string or else any other way we have to get monthyear (eg;Jan2021).

Thanks in advance

Regards  
Rakesh R

Have you tried casting the year, or using String.format() or casting? Eg

```auto
montheYear = doc['@timstamp'].value.getMonth() + String.format("%d", doc['@timstamp'].value.getYear())

```

I mentioned casting in case you were familiar with it, but you should use the `String.format()` method if you're not familiar with casting.

The problem appears to be with the `doc['TimeStamp'].value.getMonth()` call. Here's some doc on working with date fields in Painless: [Using Datetime in Painless | Painless Scripting Language [master] | Elastic](https://www.elastic.co/guide/en/elasticsearch/painless/master/painless-datetime.html)
