I use and recommend Lume [1] for static site generation, and I know it has a couple of search plugins, but I haven't used them. As others have mentioned, your search without JS requirement will be hard to implement, unless you use an external provider for the indexing and search.
"Search without JS" and "static site generation" doesn't make much sense. Without client-side search, you'll need a search product or back-end search functionality? (both of which are not "static")

How are you expecting search to work without JS? I'm pretty sure you would need either some sort of backend OR JS for any sort of search to work.
Or maybe another option would be to outsource the search part to "site:yourdomain" on google or something similar.
I use Hugo Book[1] for the documentation of FormBeep[2]
It's been super easy and I host it free on CF pages:
[1]https://hugo-book-demo.netlify.app/docs/example/ [2]https://docs.formbeep.com
https://starlight.astro.build/
The whole site can be configured in the astro.config.js file and the rest is markdown.
If you want an example you can look at sst.dev and their github repo at https://github.com/anomalyco/sst/tree/dev/www
https://zensical.org/ I have no idea how the search works though!
I have used this one : https://deepsite.hf.co/
It generates static pages using only HTML and CSS, which makes it blazing fast. It can also handle jQuery and JavaScript very smoothly.

There are some static sites that provide simple searches, but they require javascript.
You could use something like mintlify to do this. Im on their free plan and it gets the job done

Gitbook gets the job done
