I have a field "umi\_app.keyword" as string but i need to convert to two variables/objects/arrays to be able to add another string to each one (\_Critical). The part of the script looks like this

```auto
 '+doc['umi_app.keyword']+'_Critical

```

This umi\_app.keyword inside has a string [name1,name2]. In the end I would like to receive something like this **name1\_Critical, name2\_Critical**. Right now I am getting **name1,name2\_Critical**.
