@be846a9f You are right.😃 Thank you for showing me. The instance admin can maintain the YAML to adjust the available engines. Maybe after I resolve some other technical issues on my board, I will spin up another SearxNG instance.

I went thru the history of searx space commits to see why they purge/add sources... there's no coherent logic. Many of the instances they remove are still there.
