HI

I'm trying to use Groovy string methods, such as replaceAll(); in painless, but keep getting compile errors.

Heres my script:

String a = doc[Industry.keyword].value;  
String t = a.replaceAll(","," ");  
return t

I'm trying to remove all commas from the field. Are all groovy string methods supported for painless?

Painless mainly exposes core Java APIs. You can read the full API reference [here](https://www.elastic.co/guide/en/elasticsearch/painless/current/painless-api-reference.html).
