TortoiseGit filter for 2 user names

Question

I have tried to make a TortoiseGit report for the commit history, i made it to exclude 2 users from the logs, i did so for one with:

^(.(?!username))*$

But i need to exclude an additional user to. How do i filter for 2 strings?

I have already tried with following:

^(.(?!username|username1))*$

and

^(.(?!username))*$|^(.(?!username1))*$

ps. Only this filter format works for TortoiseGit

Answer 1

^(?!(?:username1|username2)$).*$ is correct.

Furthermore, please untick other search criteria than Author, and remember to tick Use Regular Expression

Note: Since TortoiseGit 1.8.7.1, you have Toggle checked filters

Answer 2

Could be this

^(?!(?:username1|username2)$).*$

or

 #  ^(?!username1$)(?!username2$).*$

 ^ 
 (?! username1 $ )
 (?! username2 $ )
 .* 
 $
