To use this contribution add it to your =~/.spacemacs=

#+BEGIN_SRC emacs-lisp
  (setq-default dotspacemacs-configuration-layers '(search-engine))
#+END_SRC
    
* Key Bindings

| Evil      | Holy    | Command                                   |
|-----------+---------+-------------------------------------------|
| ~SPC a /~ | ~C-c /~ | Summon a Helm buffer to select any engine |

* Customize it!

If you'd rather have emacs use chrome, or firefox or any other thing (=eww=) you
can have that customization. For example for google chrome you can put this in
your =dotspacemacs/config=:

#+BEGIN_SRC emacs-lisp
  (setq browse-url-browser-function 'browse-url-generic
        engine/browser-function 'browse-url-generic
        browse-url-generic-program "google-chrome")
#+END_SRC

Also if you want more search engines, just push them (do this in =dotspacemacs/config=)

#+BEGIN_SRC emacs-lisp
(push '(custom1
         :name "Custom Search Engine 1"
         :url "http://www.domain.com/s/stuff_sutff_remember_to_replace_search_candidate_with_%s")
        extra-search-engines-alist)
#+END_SRC

If you'd rather not use helm but would want a specific search engine, remember
the function generated is always =engine/search-(the name of the search engine
lower-case and hyphen instead-of-spaces-for-separation)= so you can bind that to
any key binding you want.
