Hi folks,  
I need a little help here to understand how that works.

Tried with Kibana 7.3.1, 7.6.2. 7.7.0

I've found this:  
Under "Regex" how to script a wildcard

>

Then I took a look inside the 7.7x Documentation and found the same:  
Painless’s native support for regular expressions has syntax constructs:  
[https://www.elastic.co/guide/en/elasticsearch/painless/current/painless-walkthrough.html](https://www.elastic.co/guide/en/elasticsearch/painless/current/painless-walkthrough.html)

Then I said ok lets try:

The script is invalid!  
Any suggestions?

So what is the difference between "Documentation" and "Kibana" itself

Please take a look and let me know how to use =~

Thanks  
Regards

Hi

Are Regexp enabled in your Elasticsearch.yaml, because they are disabled by default. Have a look:

[https://www.elastic.co/guide/en/elasticsearch/painless/7.7/painless-walkthrough.html#modules-scripting-painless-regex](https://www.elastic.co/guide/en/elasticsearch/painless/7.7/painless-walkthrough.html#modules-scripting-painless-regex)

Best,  
Matthias
