How to use regex in Kibana? Details given is the following page is not working for some reasons

https://www.elastic.co/guide/en/elasticsearch/reference/current/regexp-syntax.html

As per above link, To use reserved keywords as literally, escape it with a preceding backslash or surround it with double quotes. For example:

@ # renders as a literal '@'
\ # renders as a literal ''
"john@smith.com" # renders as 'john@smith.com'

Kibana doesn't allow for regex queries. That guide is for regex queries when sending direct requests to ES. For kibana syntax look for KQL and/or Lucene search syntax.
