I'm trying to generate a script field in Kibana 4 and I need to compute the difference between a date field and the current date:
(current\_date - doc['startDate'].value)
I would also like to know if there is a way I could use the date range (from-to) of every kibana query in the script field. ex:
(to\_date - doc['startDate'].value)
Any help?
Thanks!

[Lucene expressions](https://lucene.apache.org/core/5_2_0/expressions/index.html?org/apache/lucene/expressions/js/package-summary.html), which is the default scripting language, does not support date math. For date support, you can switch to Groovy, using dynamic (insecure!) or [static](https://discuss.elastic.co/t/calling-groovy-script-from-kibana/2542/3?u=tbragin) scripts.
