Hello,  
I love new kibana 4 feature that allows me to create URL based on variables. It's brilliant thank for that.  
It works just fine when I use number value doc['variable'].value or like this \_source.variable

But when I reference string value I get errors.  
Is there any other way apart from duplicating the variable in elasticsearch and formatting it directly as new\_variable  
to achieve something like that ?

Thanks & regards  
Marcin

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). More on that in this thread: [Calling groovy script from Kibana](https://discuss.elastic.co/t/calling-groovy-script-from-kibana/2542/6)
