How do i crawl specific video info on youtube based on 3-4 keywords

Hi All,

I would like to crawl video info from youtube for few specific keywords.

and the out put i am looking for is video title , Video Description ( optional ) , Video URL.

Can some one advice me how to take this forward.

Crawling is not searching. While you crawl, you just discover child pages of root urls in an iterative way. There is not “jumping” to specific pages according to the requests you have.
When crawling is done, you can search. But you cannot steer the crawler to discover exactly that.
