Function: word-search-forward
word-search-forward is an interactive and byte-compiled function
defined in isearch.el.gz.
Signature
(word-search-forward STRING &optional BOUND NOERROR COUNT)
Documentation
Search forward from point for STRING, ignoring differences in punctuation.
Set point to the end of the occurrence found, and return point.
An optional second argument bounds the search; it is a buffer position.
The match found must not end after that position. A value of nil
means search to the end of the accessible portion of the buffer.
Optional third argument, if t, means if fail just return nil (no error).
If not nil and not t, move to limit of search and return nil.
Optional fourth argument COUNT, if a positive number, means to search
for COUNT successive occurrences. If COUNT is negative, search
backward, instead of forward, for -COUNT occurrences. A value of
nil means the same as 1.
With COUNT positive, the match found is the COUNTth one (or first,
if COUNT is 1 or nil) in the buffer located entirely after the
origin of the search; correspondingly with COUNT negative.
Relies on the function word-search-regexp to convert a sequence
of words in STRING to a regexp used to search words without regard
to punctuation.
This command does not support character folding, and lax space matching
has no effect on it.
Probably introduced at or before Emacs version 23.1.
