Basically every Elixir package's docs include search based on Lunr, as it's included by default by ExDoc[1]. It's quite good.

[1]: https://hexdocs.pm/ex_doc/

We use at endoflife.date, and are fairly happy. We had to add a workaround to get some search terms working (because of how it does stemming, searching for BSD wouldn't show openbsd earlier): https://github.com/endoflife-date/endoflife.date/issues/4924), but it is still not 100% perfect: searching for fusion still doesn't get you coldfusion.

I use https://pagefind.app/ for search on my website. It’s really easy to add to a static site.

I use Lunr on allaboutberlin.com. It's simple and effective, but searching the whole content would have required loading more files than I was comfortable with. Therefore it only searches titles and descriptions.

There are probably workarounds, but it's the only limitation I can think of. Otherwise Lunr just works.

I been using this project (seems to be abandoned now but still works) https://stork-search.net/

Works great.

I think https://develop.kde.org/docs/ is using lunrjs for search, but downloading and parsing almost 2MB file of search data creates some hiccups on website during load.

i use flex search https://github.com/nextapps-de/flexsearch

vitepress seems to use https://github.com/lucaong/minisearch/ and the vitepress docs I have built and used are good.
