Hi

Try this

| makeresults 
| eval user="[email protected]" 
| rex field=user "(?P<user>^[^@]+)"

or

| makeresults 
| eval user="[email protected]", result = mvindex(split(user,"@"),0)

Here is one way to do it

| makeresults 
| eval user="[email protected]" 
| rex field=user "(?<username>[^@]+)@.*"
| table user username

Simplest regex you can use could be this:

| rex field=user "^(?<justUser>[^\@]+)"

Which will extract just the user from the field user into a new field named justUser.

A more accurate and faster regex would be something like https://www.regextester.com/19

Hope that helps,
