I know that anyone can select YouTube's Filter & Explore, and filter results by: Type of results, such as Videos, Channels, or Playlists, Upload date, Subject category, Video length, Video quality. Features, such as Closed captions, Partner videos, or Rentals. You can also sort your results by: RelevanceRating, Upload date and View count. And anyone can search YouTube via Google, in Advanced Search by "search within a specific website". Is there more to know about YouTube search? Are there other ways to specifically search there?
