Moved search to documentation index page

Resolving #230

There's an issue in autocomplete results view.
The z-index property seems alright still it isn't filling up the area properly.

It's not an issue with z-index, the .hero section has an overflow: hidden on it.

Could you actually move it down into the body like this though:

Thanks for the design. I'll on it.

I think "Search documentation" won't fit in into the navbar. We should either make it "Search docs.." or adjust the width.
Make a call. I'll do it!

Sorry, I got to tweaking and made a bunch of changes

[dhruvdutt]

Seems perfect! 💯

What do you guys think of having the search bar in the header as well? See #284
