It's features like this that have continued to keep YouTube on top, I suspect. I've actually had a project recently which called for me to search through videos and they are by far the least heartbreak-inducing among the big video sharing sites.

I was in search of advance search options in youtube any finally i got help from this post.thanks

My internet connection is slow,sometime it came in my mind that youtube must have some option for search that can say something about quality or size of video to search.

I want ti be able to search on youtube according to rating.

this option is ridiculous.i give you an example,let say,to count number of students in a class,we say,number of ill students+no of students not ill,as this is common sense,but this formula does'nt work in youtube,that makes it hard to trust on it's figures,even,total no of videos excluding(not suitable for minors)is more than total no of videos including(not suitable category),now tell me how is that possible? write any word and set videos uploaded today,let rest of the options remain general and press search...............TRY IT YOURSELF

@FADI:

The number of results is just an estimation because it's difficult and time-consuming to find the exact number.
