Hi Isedrof,
I don't want to be mean nor rude; but like some famous answers member once said: You need to learn to walk, before you run
@rich7177 and @woodcok pointed out some information.
I think it can be done, but it is not worth the effort! Because you would have to get each single value for the user_name normalize them and compare each single character one by one. But as I said, this will take some effort and if I recall the trouble you had just to get this search working ...... Well, see You need to learn to walk, before you run
My suggestion: clean up your data! Have the user_name in all sources to be the same and your done.
Most of my costumers check their data before it will be ingested into Splunk and if the data is not in a useful format (any key=value pair will work fine) they simply reject it. This may be harsh, but it will pay off in the end!
cheer, MuS
