@83500bcd6348a4be6df4 The best way to tests for a multiline pattern is to use a go playground.

I've tested your original data, you could use the pattern = `=-=-=-=-=-=-=-=-` and set negate option to true.

You can see the code and the result [there](https://play.golang.org/p/VZgj_td6kRj)

Since Filebeat is written in go we don't have a specific example in other languages.  
But the regular expression is using the RE2 syntax and you can see all the details at our doc page at [https://www.elastic.co/guide/en/beats/filebeat/current/regexp-support.html](https://www.elastic.co/guide/en/beats/filebeat/current/regexp-support.html) or the official golang doc at [https://github.com/google/re2/wiki/Syntax](https://github.com/google/re2/wiki/Syntax).
