Where can I find more information on using it for user-facing search? The repository [0] starts with "Cloud-native search engine for observability (logs, traces, and soon metrics!)" and keeps talking about those.
Their original breakout demo was on Common Crawl: https://common-crawl.quickwit.io/
But thanks for pointing it out, I hadn't looked at it in a few months, it looks like they significantly changed their pitch in the last year. I assume they got VC money and they need to deliver now.
I tried "England is" and a few similar queries. It spends three seconds then shows that nothing is found.
The blog post about the demo is from 2021 and they haven't promoted it much since. I'm surprised that they even kept it online, according to the sidebar it was ~$810/month in AWS at the time.
