I find TED talks are really hard to find, if you don’t remember its exact title and/or speaker. The difficulty is that often you remember the basic idea, but not the keywords (since it might not be in a field you necessarily study).
So for example, you could think “Oh that one with the headband where they controlled the computer by thinking about it”, but not know to search for BCI, or Brain-Computer Interfacing, if that’s not your field. Searching for “controlling computer with thoughts” probably isn’t going to get you anywhere either.
Besides that, I don’t think their tags are all that comprehensive.
