Actually, I like ggd/hello word/e better.

gg - go to beginning of the file
d/hello word/e - delete from current cursor position to the END of the
match (because of "/e") for "hello word"

I believe that the regex with \_.* in it will take much longer because
it will involve backtracking, since regular expressions are greedy.

If you're determined to do it with regex, this would probably be
faster:

:%s#\%^\_.\{-}hello word##

\%^ - start of file
\_.\{-} - AS FEW AS POSSIBLE of any character, including line endings
hello word - desired keyword text

See :help \%^ for an example of usage to find the first occurrence of
a keyword in a file.

But, that's getting to be a LOT more complex than the simple methods
using d/ that have already been discussed.
