I am searching a particular regex pattern in the discover tab through KQL and Lucence but I got the error `Expected ":", "<", "<=", ">", ">=", AND, OR, end of input, whitespace but "\" found. log:"api.mydomain.com" AND ' \s5..\s' ----------------------------^` Here is the query I want to search **log: "[api.mydomain.com](http://api.mydomain.com)" AND ' \s5..\s'** How to do that? ---

Hi @rishabhtryroll, KQL doesn't support regular expresions. Have you tried with Lucene?[https://github.com/elastic/kibana/issues/46855](https://github.com/elastic/kibana/issues/46855) ---
