(isearch-forward-word &optional NOT-WORD NO-RECURSIVE-EDIT)

Do incremental search forward for a sequence of words.
With a prefix argument, do a regular string search instead.
Like ordinary incremental search except that your input is treated
as a sequence of words without regard to how the words are separated.
See the command `isearch-forward' for more information.
