FOREWORDS

I don't mean the snippet at the bottom of this gist to be a generic plug-n-play solution to your search needs. It is very likely to not work for you or even break things, and it certainly is not as extensively tested and genericised as your regular third-party plugin.

My goal, here and in most of my posts, is to show how Vim's features can be leveraged to build your own high-level, low-maintenance, workflows without systematically jumping on the plugins bandwagon or twisting Vim's arm.
