By default Kibana 4 scripted fields use [Lucene expressions](http://lucene.apache.org/core/4_9_0/expressions/index.html?org/apache/lucene/expressions/js/package-summary.html), which currently only operate on numeric fields.

You can turn on static Groovy scripts, which have more advanced scripting functionality (note dynamic Groovy scripts are no longer recommended) -- for more discussion on how to do that in Kibana 4 please see [this thread](https://discuss.elastic.co/t/calling-groovy-script-from-kibana/2542/3).
