Enable site wide search for a collection of flexdashboards using fuse js

Trying to understand how I can implement this within flexdashboard. Live example here if you click search.

The goal is to be able to create a site and navigate nicely between rmd and flexdashboard content.

Currently you can render a site and embed a flexdashboard like this example here from Rami. This shows how to implement within package down, but the same applies to blogdown, or render_site via rmd site generator.

I think it'd be useful to just be able to search in order to navigate.

# hypothetical YAML
---
title: "Navigation Bar"
output: 
  flexdashboard::flex_dashboard:
    navbar:
      - { title: "Search", href: "#", align: left }
