Remembering a regexp across searches

Remembering a regexp across searches

[Michael Preminger]

Hello!

Maybe something I would expect to find in the FAQ, but to no avail:

I need to do repeating incremental searches of regular expression.

when I find what I was looking for - I need to do some changes 
(manually), and then search for the next occurrence corresponding to the 
same regexp.

Sometimes the regexps are complicated, and retyping them in the 
Iserach-buffer is tedious.

How do I avoid this re-typing? Is there a way to make emacs "remember" a 
regexp and re-use it in a handy way?

Thanks

michael

Just type another C-s and you are set.

So if you did your first search with 
C-u C-s something
then
C-u C-s C-s

will repeat the search.

Or, if you need more history, meta-p and meta-n are your friends :-)
There are  a couple more nice things in isearch, and they are
explained in the "Emacs Manual".

As I said before, I never repeat myself.

;; recalling from search ring
(define-key minibuffer-local-isearch-map [up]         'isearch-ring-retreat-edit)
(define-key minibuffer-local-isearch-map [down]       'isearch-ring-advance-edit)
(define-key isearch-mode-map [up]                     'isearch-ring-retreat)
(define-key isearch-mode-map [down]                   'isearch-ring-advance)

Then up/down arrow scrolls through the search history.

M-x ESC ESC recalls the last command, and also has up/down arrow history.
