This sounds like a fun problem to solve as a developer. A web application could be written that:
- Takes incoming requests from the UI (presumably SearXNG-like in appearance)
- Hits multiple instances at once
- Proxies the results from the fastest successful instance
If SearXNG offers an API you could even ditch the proxying of results. If you got really fancy you could store stats on which are the fastest/slowest and act on that in the future.
I’ve seen some of the nicest vehicles on the planet waste everyone’s time doing this stupid maneuver and I’d gamble they all had rear cameras too.
