I want to match certain keys and group them as O1 and others set of Keys to O2, and then use the fields
If i have to use rex field then in that case I should create two fields?

Have you understood?

Yes I think that this is the easiest way to do it. Later you can use e.g. coalesce to select which value you have in current event. Or use case with isnull/isnotnull conditions.

Hi

What issue you are trying to solve?

regex command select rows which are matching it and drop others. So you cannot use it like this.

If you want to pick part of event to a new field then you should use rex command not regex.
