Hi, I currently have a filter with nine "or" statements that look for a few different strings in log messages, then applies a tag. I tried a regex similar to this, but it wasn't matching on anything: if "(foo|bar|foobar)" in [message] { mutate { add_tag => "mytag" } } The only way I could …

How do you do multiple "OR"s in a filter?

Try

if [message] =~ "(foo|bar|foobar)" {

"in" does array membership testing and substring matching. =~ does regexp matching.
