Become a MacRumors Supporter for $50/year with no ads, ability to filter front page stories, and private forums.
I don't use Alfred, but you can search MR Forums with Google. Just add the following to your Google search terms:
site:forums.macrumors.com​
 
It seems that based on the search method employed by MacRumors Forums you need to do a modified google search as mentioned above.

You can still perform the search within Alfred by adding the following URL to Custom Searches:

http://www.google.com/search?q={query}+site:forums.macrumors.com
