For several years, I've been happily using multiple-cursors with phi-search to run interactive searches with several cursors at once with Emacs 23. I would create my multiple cursors, then run phi-search as needed to navigate, and edit when I arrived at the point I wanted.

My configuration looked like this:

(require 'multiple-cursors)
(require 'phi-search)
(define-key mc/keymap (kbd "C-s") 'phi-search)
(define-key mc/keymap (kbd "C-r") 'phi-search-backward)

But in Emacs 24, phi-search with multiple-cursors active will only search for a single cursor, and leave the others unchanged. Is there any way to get isearch like navigation when there are multiple cursors on the screen, assuming I'm using a recent Emacs?

    Check your .mc-lists.el file and make sure that phi-search is listed under mc/cmds-to-run-for-all and not under mc/cmds-to-run-once. – nispio Dec 13 '16 at 17:37
  • Yes, I have done this. It worked fine in Emacs 23, but it appears to be broken after upgrading to Emacs 24. I have also updated to the latest multiple-cursors. Can any confirm that this is working correctly for them with Emacs 24+? – emk Dec 13 '16 at 20:43

    It works for me in both emacs 24 and 25 with deleting .mc-lists.el and running emacs -q. Can you reproduce in this scenario? – nispio Dec 14 '16 at 0:10

    Also, make sure you are not using packages in emacs 24 that you byte-compiled with emacs 23. This could cause unexpected behavior. – nispio Dec 14 '16 at 0:22
  • I've checked emacs -q, but I'm still seeing failures. Next, I want to try this on a completely clean user account to make sure Emacs package-install isn't picking up stale byte codes from anywhere. – emk Dec 14 '16 at 12:15

I also have the same problem, finally I decided to add this package:

https://github.com/knu/phi-search-mc.el

So the complet setup is multiple-cursors, phi-search adn phi-search-mc, and having this file configuration for multiple cursors and phi-search it works well:

;;; file --- my-multiple-cursors.el
;;; Commentary:
;;; my configuration for multiple cursors
;;; Code:
(require 'multiple-cursors)
(require 'phi-search)

(define-prefix-command 'toni/mc-map)
(define-key ctl-x-map "c" 'toni/mc-map)

(define-key toni/mc-map "c" 'multiple-cursors-mode)

(define-key toni/mc-map "l" 'mc/edit-lines)
(define-key toni/mc-map "n" 'mc/mark-next-like-this)
(define-key toni/mc-map "p" 'mc/mark-previous-like-this)
(define-key toni/mc-map "a" 'mc/mark-all-like-this)
(define-key toni/mc-map "un" 'mc/unmark-next-like-this)
(define-key toni/mc-map "up" 'mc/unmark-previous-like-this)
(define-key toni/mc-map "i" 'mc/insert-numbers)
(define-key toni/mc-map "h" 'mc-hide-unmatched-lines-mode)

(define-key toni/mc-map "d" 'mc/mark-all-symbols-like-this-in-defun)
(define-key toni/mc-map "r" 'mc/reverse-regions)
(define-key toni/mc-map "s" 'mc/sort-regions)
(define-key toni/mc-map "\C-a" 'mc/edit-beginnings-of-lines)
(define-key toni/mc-map "\C-e" 'mc/edit-ends-of-lines)

(define-key toni/mc-map (kbd "C-s") 'phi-search)
(define-key toni/mc-map (kbd "C-r") 'phi-search-backward)

(phi-search-mc/setup-keys)

(add-hook 'isearch-mode-hook 'phi-search-from-isearch-mc/setup-keys)

(provide 'my-multiple-cursors)
;;; my-multiple-cursors.el ends here
