Here's a technique to get search results for all posts in the last "X" days, where "X" is a number. The following string, when copy/pasted to your browser address line will create a search and display all posts from the last "X" days.

You can just copy and paste or just type this string into your browser anytime, replace the "X" to run this query.

or

Create a shortcut to the forum, put it on the desktop, alter the url to read as shown above with the number of day(s) filled in. Then double clicking on it loads the search automatically. If you're not logged in, you get the log in screen first then the search results. Thanks to "Logician" for sharing the code string.

P.S. If there is a way to filter the search results for a specific Forum Category, I'll be sure to pass it along when/if I find out.
