TIL https://www.findx.com is back up and running after shutting down a year ago.
"This is a re-launched version of Findx. Previously, we attempted to build our own open-source search engine which had its own search index (more about that here ). This new version uses data from Microsoft (Bing). More things are in the works, but we cannot reveal more at this time."
