I don't understand your use case. If I know the exact title of the video, it finds it. Everytime.
If you try to describe a non-popular video it just becomes a crapshoot on what to give you if there's no word/tag watching. You'd need some hint of the channel name or something. The volume of low viewership videos is incredibly high.
Can you give me a real example of something you've tried to do?

This is unfortunately not true. I have a little channel and there have been times when searching for the exact title of some of my videos did not return it in the results at all (searching with quotes or not). Cannot reproduce now because the search algorithm has now started liking me.
