use for example your library vulnerability modifier

/hello/i

It would also be wise to add \ b, the word separator, so you don't select "ahello".

/\bhello\b/i

+4

Depending on your regex engine there should be a way to specify case insensitivity.

For example, in Perl:

/Hello/i

or Python:

re.compile(r"hello", re.IGNORECASE)

Alternatively, you can do it manually for each character:

[Hh][Ee][Ll][Ll][Oo]
