Not so sure if it's a bug, but I get quite unexpected results when search videos. This doesn't happen on the main search.
Context: Eischmann held several lectures at OpenAlt conference, but when I search for: „konference openalt eischmann“ in videos, I get twelve results about the second world war, which only contain words Eischmann, but no konference nor openalt. Only after that come results that have all three words in the title of the video or channel.
I'd expect to get the recording of the openalt conference first.
