The default language for Kibana scripted fields is [Lucene expressions](http://lucene.apache.org/core/4_9_0/expressions/index.html?org/apache/lucene/expressions/js/package-summary.html), which can only work with integers at this time.

You can instead use Groovy scripts, which can operate on strings, but take care to do so in a secure manner (dynamic scripts are insecure, so you must use static scripts).
