The configuration for PageFind needs to respect the relative path to where it is installed for linked content. This will let the PageFind work on an individual site on a development machine and when the website is published via GitHub.

Here's an example script element.

<script>
    window.addEventListener('DOMContentLoaded', (event) => {
        new PagefindUI({ 
            element: "#search",
            basePath: "./",
        });
    });
</script>

The second problem is that you should be able to link directly to a search result via the q= parameter. I need to integrate that into this JavaScript template.
