I didn't try it with comments, but they also seem to be censoring the word "yoga" from the search for me. If I write "yoga" (and any other words along with it), no suggestions are shown and it doesn't get saved in the search history.
I found out about it after occasionally flipping through the TV channels and being surprised to come across a local TV show about yoga for kids called "Yoga com Histórias" (yoga with stories), with animated characters and model kids doing the poses while a narrator instructed the steps. There was even a cheerful opening theme song saying "yoga does you good, yoga does you good" at the chorus. I don't watch TV for years anymore and it was just an occasional flip to see if there was anything worth watching, but this is something quite interesting. But when looking up the name of the show on YouTube, what I described above happened, even though there are actual video results of it.
