I use duckduckgo. It is Bing but with more privacy. You could try also searx, swisscows, startpage or qwant

Headless server with debian and mldonkey, I search on ed2k/kad network and public trackers for bittorrent. I use plex to stream to my devices.

Perfectly alive with aprox 100k daily users

I compile the source code: git clone, cd mldonkey, ./configure, make, make install
