What's your mapping for the "rf\_tag" field in Kibana index pattern? Could you show a screenshot of that?

The Regexp query is different from regex in the Lucene query syntax, so you may need to play around with that separately: [https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#\_regular\_expressions](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#_regular_expressions)
For what you're trying to do, I wonder if you even need a regular expression, you might just be able to use wildcards.
I've had success with the following approach for doing wildcard searches:
- Search against raw (or not\_analyzed) versions of the string
- Use backslash to escape special characters

@tbragin,medcl have help me solve this problem, this case happen when search uppercase, we can add lowercase\_expanded\_terms:false to search url then run well
