Why isn't my video searchable? I gave my mom all of my video's tags so she could find it and subscribe to me, but my video didn't show up at all. I had to send her a direct link. Why does this happen?

Why doesn't my video show up in search? That's my biggest problem and I need help. Yes, I only have one video up right now, but it was just because I wanted to make my channel searchable before I made

I uploaded my first video, hoping that would make my channel searchable for my parents to subscribe to, but it's not searchable either. I haven't found an answer but I would like one as well.
