This is what I’m using with my Astro personal blog. It’s awesome.

Interesting, is that a more complete variation of fuse.js? (Just pluged-in fuse.js into my static jekyll blog)

I think Pagefind is focused on the whole experience of searching pages, like with default UI widgets, easy page indexing, and handling larger sites. fuse.js seems to be a fuzzy-filter function on JS data, not handling the site integration.

Pagefind uses an index that is created ahead of time and stored as numerous files on a static site. It then downloads just the part of the index needed to complete the search. This means that you can search vastly more data than could be loaded onto a browser.

This is just what I wanted, thank you for that!

Me too! I'm a huge fan. I use it for all my static sites.
