HOWTO Programatically construct Google News Search URL so that I can open a new browser window/tab with it

In one of my apps I want to open a new window/tab for a "google news" query. Is there an official documentation where I can look up what all different google search parameters mean & what encoding I need to do for certain parameters like time-range. I got hold of some unofficial links like this but it is not exhaustive. I dont want to reverse engineer the sample queries that I fired on Google News page.

My goal is to just simply programatically construct the google search url & direct the user to it, I do not want to get just the JSON etc search result else I would h开发者_JAVA技巧ave used the Google News Search API, which BTW is deprecated.
