Hello

My text field is in this form AAA\_ΒΒΒ.

I used the split filter  
split =\> ["message" , "\_"]

and the result is  
message AAA, BBB

and now I want to delete AAA from message.  
any ideas?

thanks,

---

This should also do it:

```auto
    split => ["message" , "_"]
    mutate {
      replace => { “message” => “%{[message][1]}”
    }

```
