I essentially wish to match every line that DOES NOT contain this string "Hello"

Example:

sdfsdoifdoskf
fdgokfdghodfkg
hello
fdojgohdfgjkdfg
gfobjobhkdfokgdfg
dofjkdsf hello dfgkdfogdfg
xcvmxhckvmxck
fogkdfhokg
hello

I attempted this Regex pattern : ^((?!hello).)*$

No matches found.

Basically i want to remove every line that does not contain the string "hello" using notepad++

^((?!hello).)*$ works in Notepad++ 6. I wonder if it's better than this: ^(?!.*hello).*$
