Simple (I hope) Search Request

[Shan]

This probably exists, but I could not find it.

I want to add a button to one of my menus that will simply do a search for all threads that are either now or have changed within the last 24-hours. When I try to do this in the Search screen, it was a keyword or poster name. I just want it to return all new or changed posts.

Can anyone tell me the Querystring to send or the code to create a button?

Thanks in advance,

Shan
