Hi

if you want to pick those values from events then you need a rex and if you want to select events which contains that kind of parts, but don't want to select those to the new fields then you should use regex.

Hi

You could try this (I suppose that you have above data already in splunk _raw field).

... <your search> ..
| rex "From: <(?<from_mail_id>[^>]+)> To: <(?<to_mail_id>[^>]+)>"

You could use e.g this

...
| rex "(?<count-1>\d+)-(?<count-2>\d+)-(?<count-3>\d+)-(?<count-4>\d+)"
