I searched for "syndey olympics", Kagi returned no results.

I expect the search engine to be resilient to minor typos like this. "No Results" for such a common search term is unexpected. (14 results are returned when spelled correctly: https://kagi.com/search?q=sydney+olympics)
I've noticed the No Results page more often recently, though this is the only concrete example I have captured. That leads me to believe this is an introduced bug, not one that has been present in Kagi for a long time.
