I'd like to select a lines with does not contain a word SCREEN. I tried the following regex (?<!SCREEN).+ but it seems not to work - selects all the lines. Why doesn't it work?

The short answer: ^((?!SCREEN).)*$

This is inspired by https://stackoverflow.com/questions/406230/regular-expression-to-match-a-line-that-doesnt-contain-a-word which contains a full explanation

    I think ^(?:(?!SCREEN).)*$ would be more efficient

Another try for this case: (SCREEN){0}.*$

Hope that can help.
