I added a client-side search functionality to this static blog.

Similar to what is explained in this article by Stephan Miller, I added a search functionality to the blog.
The challenge was to do this while keeping the blog a static generated site.
Thus the choice to do all of the search client-side in JavaScript.

The way my current implementation works, is that there is a JSON blob with all the posts ever written in this blog.
This is loaded to the browser and indexed using Lunr.js.
The resulting search index is then used to provide the search functionality.
It comes with some convenient built-in search modifiers such as +, - and *.

To avoid reloading the whole JSON blob for each follow-up query on the search page, it intercepts the default form submit action and handles the search client-side.
Thus re-using the computed search index and saving the additional roundtrips accross the network.
