I've searched for iAppleBytes 18.6 where "iAppleBytes" is the name of the YouTube channel, and "18.6" is video name.
Results I've got:
iAppleBytes - youtube channel link (good, expected)
random videos that do not belong to iAppleBytes channel, but because of indentation, I was misled into thinking they belong to the channel.

I expected to have a link to a YouTube channel, and if it doesn't contain a video that I want, other videos should not be indented, but instead be on the same level as the first one.
