How to extract trailing numbers from a string with rex

[hmbisht]

I'm trying to extract a string (alphabets and underscore) from a given string which can contain any number of numeric values in the end.

 rex field=_raw "type: (?.*)\d*$"

ex.
type: alphabets123 | alphabet
type: extract1 | extract
type: write_regex23| write_regex

| makeresults 
|  eval x="type: write_regex23" 
 | rex field=x "\:+(?<extract>.*?)\d+"

replace x by your source field and remove makeresults
