This is all pretty awesome. However, with regard to search, the zero latency is indeed fast, and this is because it is client-side entirely. It appears to be hand written for this site.

I think the quality of search recall and ranking could be improved though. It has zero tolerance for misspelling for instance, and cannot match partial words while you are typing the terms. Still, it is pretty cool. And open source too, which is even cooler.

Looks like a static site built with Jekyll. Not sure which search plugin they're using here (it may be one of the default Jekyll plugins rather than bespoke code), but I've seen Jekyll sites that use Algolia for search results that are smokin' fast and extremely accurate.

The search code appears to be hand-written though. You can find the commit history for the core search functions here: https://github.com/buddhist-uni/buddhist-uni.github.io/blame...

It's kind of neat that they did hand write it in a way. A fun project I'm sure. And they even made it run in a worker to keep things even more quick and responsive.

"Zero latency search" sounds nice, but searching for either "prajñā" or "pāramitā" (with or without diacritics) yields 0 results. FYI, those are absolute basic terminology of Mahayana Buddhism (Mahayana texts constituting a massive part of the Buddhist corpus).

After a quick glance I would say it is a Therevada "University" with a few texts (but no courses) on other Buddhist schools.

I agree he did a great job designing his site. :)
