How to give every event all fields that occur in any event already processed in search

[snreichel]

So I've managed to make the first few events be those which have the 25 extra fields, but how do I make all following events have these fields too, even with null value?

You need the filldown command:

Did you try fillnull command? https://docs.splunk.com/Documentation/SplunkCloud/6.6.0/SearchReference/Fillnull

your current search | fillnull value="NULL"

OR just add a table command in the end to list all the field that you want to be listed even if no values exists

your current search | table ..list..of..all..fields..to..show
