YouTube Searching

Everybody's been to YouTube before, right? Then you know that you have the option of searching keywords for a movie. When you do search, the movies are listed in a certain order. Does anyone know what determines that order? I don't think it is related to the amount of views. Maybe it's the amount of times the keyword shows up in the description.

If anyone has the answer (or any idea) please post them here.

its shown in relativity to the keywords.

But, i made a video with. Then I searched it. A video had 2 tags and it matched both of them, but the search matched three of mine and mine was displayed after that one. Why?

hmmm, maybe because their video is older. that often has something to do with it

Nope, not that either.
