Permanently Changing Search Option

Permanently Changing Search Option

[Bill]

I'm sure there must be a way to permanently change the Emacs's search
options so that C-s always searches word by word and not one letter at
a time, as I type. They key word here is permanently. I know it can be
done using C-s Enter, but I'd like Emacs to do this using C-s instead.

Thanks for any assistance you can offer.

(setq isearch-word t) ; or is setq-default necessary?

Kevin:

Thanks for the info.

I'm not quite clear what you meant to say above. 

Can you elaborate for me?

Thanks

This is Emacs Lisp:

(setq isearch-word t)

Emacs Lisp is used to customize and extend Emacs.  Emacs customizations
are made persistent for future sessions by saving them in your ~/.emacs
file.

I just now put (setq isearch-word t) in my .emacs file. Restarted a session
in Emacs. But the search remains incrimental.

Any further thoughts?

Appreciated.

Ah, I see now that isearch-mode resets isearch-word each time it's
called.  Try this:

(add-hook 'isearch-mode (lambda () (setq isearch-word t)))

Sorry for the delay in trying out your suggestion.

Yes, these two .emacs additions do just what I needed.

Thanks much.

Put this into your init file (~/.emacs usually)

(global-set-key (kbd "C-s") 'search-forward)

      Forward and backward word searches are implemented by the
      commands `word-search-forward' and `word-search-backward'. These
      commands may be bound to keys in the usual manner. They are
      available via the incremental search commands both for
      historical reasons and to avoid the need to find separate key
      sequences for them.
