Number of YouTube search results not showing

Since I didn't find a way to do that on Youtube anymore, I've created these new generic Google video searches to get localized results:

http://www.google.com/search?hl=en&q=%s&gbv=1&ie=UTF-8&tbo=u&tbm=vid&pws=0

http://www.google.com.br/search?hl=pt-BR&q=%s&gbv=1&ie=UTF-8&tbo=u&tbm=vid&pws=0

It seems not possible to do what you want. The blog cited in the other answer states search commands that don't work today (e.g., Apple, this week returns videos from 3 years ago).

There is an API reference showing how you could do it with GET, and there's an advanced search that also modifies the URL.

It's possible to do what you want, but not how you want to do it.
