Elaborate?
If you delegate queries to e.g. google or bing at that rate, you'll be ip blocked in a heartbeat.
btw thank you for Marginalia! The spirit of the small web is very important to me.
Like I don't mind automated access to my search engine, I even offer a public API to the effect, that you can in fact hook into SearXNG. What I mind is when one jabroni with a botnet decides their search traffic is more important than everyone else's and grabs all the compute for himself via a sybil attack.
Honestly, I just use Kagi. Though I need to find some way to limit my searches to 300 per month.
although existing searx instances have been run for years and they don't seem to be dropping like flies...
