Search strings which are not starting with ****

[kmmanu]

Tthere are logs like below three lines

user name is "fgt56wer"
user name is "****89g4ty5"
user name is "jks4qw"

I want to avoid all lines which starts with user name is "**** from the splunk search result
My expected search output is below :-

user name is "fgt56wer"
user name is "jks4qw"

Can anyone help me to get the regular expression or search query ?

Try:

... | regex _raw!="user name is \"\*\*\*"
