FYI, the search at the bottom of HN's site relies on Algolia and its has been down since November 27, 2022. New content is not showing for 2 days:

https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...

My iOS, MacOS and Android client app HACK which relies on Algolia for a tiny portion of the app (the Chronological section) isn't able to show the new content. The vast majority of the rest of the app works fine.

Issue filed on Github:

https://github.com/algolia/hn-search/issues/233

Looks like the issue is resolved now.
