Package for GNU Emacs that shows an overview during regex searching.
The package uses the ivy back end for the overview, see also
swiper-helm.
There's also a ten minute video demo.
Ivy is a generic completion mechanism for Emacs. While it operates
similarly to other completion schemes such as icomplete-mode, Ivy
aims to be more efficient, smaller, simpler, and smoother to use yet
highly customizable.
To try Ivy, just call M-x ivy-mode. This will enable
generic Ivy completion, including specific completion for file and
buffer names.
Install the swiper package from MELPA / GNU ELPA.
The manual is available as HTML.
After installing from MELPA, the manual is also available through the (ivy) Info node.
The source file for the Info page is here.
Ivy and Swiper wiki is here: the wiki.

Any legally significant contributions can only be accepted after the author has completed their paperwork. Please see the request form if you want to proceed.
The copyright assignment isn't a big deal, it just says that the copyright for your submitted changes to Emacs belongs to the FSF. This assignment works for all projects related to Emacs. To obtain it, you need to send one email, then send one letter (if you live in the US, it's digital), and wait for some time (in my case, I had to wait for one month).
The basic code style guide is to use (setq indent-tabs-mode nil). It is provided for you in .dir-locals.el, please obey it.
Before submitting the change, run make compile and make test to make sure that it doesn't introduce new compile warnings or test failures. Also run M-x checkdoc to see that your changes obey the documentation guidelines.
Use your own judgment for the commit messages, I recommend a verbose style using magit-commit-add-log.
