How to Remove Rows With "NULL"?

Greetings Splunk Community,

I am currently working on a search and I am trying to drop rows that have "NULL" in them. The problem I am running into is that some of my rows with "NULL" have things like "nullnullNULL" or "nullNULL".  Is there a way i can remove the any row that has the "NULL" value regardless of other info in it?

Thanks in advance!

If you want to exclude all events that have the string NULL (case sensitive) anywhere in them, do

| regex _raw!="NULL"

You can also match against single fields
