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:
Then I said ok lets try:
The script is invalid!
So what is the difference between "Documentation" and "Kibana" itself
Please take a look and let me know how to use =~
