Bing News Search exploratory RSS view

Hi all, lately I was experimenting with Bing News Search, specifically with RSS format.

Example url: "bing.com/news/search?q="banking"+&format=rss "

I was wondering, if there is a way to increase the number or results directly from url? I tried working with &count=, however it only works for lower numbers like 2, 3, but if I try to put somehing like 20, 30 it seems like there is a set upper limit for returned articles - around 14 articles max.

Example usage: "bing.com/news/search?q="banking"+&format=rss&count=20 "

The second question is if there is a url-direct way to return results only from specific date?

Thank you very much for help, I really appreciate it
