Steps to reproduce:
Search for "Vladimir Prelovac" and switch to "Videos".
You'll see only videos about Putin.
Expected behavior:
I expect the search results to show videos related to @Vlad :-).
Debug info:
Region does not seem to matter, happens with (EUROPE-WEST2 and US_WEST), tested on Firefox.
Interestingly: Searching other people named "Vladimir", e. g. "Vladimir Kramnik" seems to work fine.
In any case, searching on YouTube directly gives relevant videos. I suspect Kagi is prioritizing videos with higher view counts somehow, but who knows.
