One of the consequences of the effectiveness of click-bait titles on youtube is that searching for videos you watched historically is extremely difficult, because quite often the primary thing in the video is never mentioned in the title. The descriptions are almost universally used to store common links that are about the channel not the video and the consequence of this is that click-bait titled content is very hard to find after the fact. The other problem is quite a lot of channels are testing one title and then changing to another, the video wont then be found using the initial title and so even if you do remember elements of the title the channel may have made that impossible to use some hours or days later as another title with better performance was used.

I can see a need for search in the contents of the videos but I don't want to specify the channel, I likely don't know especially since channels can also change their name.
