get_search method does not have the "UPLOAD DATE" filter which is available on the YouTube's website. The thing is, when "SORT BY" "Upload date", it returns different results depending on whether "UPLOAD DATE" is set to "Today" or it is not set. From my experiment, get_search returns the result that is the same searching YouTube's website without setting "UPLOAD DATE".
I need this "UPLOAD DATE" argument, because without this, the search does not return a lot of the new videos.
If adding this argument is technically infeasible, due to YouTube's encryption, obfuscation, or something like that, please close this issue.
Search on YouTube's website

Searching for "puppies", with "SORT BY" = "Upload date", "UPLOAD DATE" = "Last hour"

Searching for "puppies", with "SORT BY" = "Upload date"
