search emacs buffer like helm grep?

Question

You can search for word list ('hello', 'world') by typing world <space> hello in helm-grep

I currently use ido for buffer switching, and I have to type world C-<space> hello to filter by two words.

Is there a buffer switch mode which offer the filtering by words separated by just a space?

Answer 1

Try this:

(defun my-ido-setup-hook ()
  (define-key
      ido-buffer-completion-map
      " "
    'ido-restrict-to-matches))

(add-hook 'ido-setup-hook 'my-ido-setup-hook)
