TigSource Blog bug

Hello everyone. I'm Just jposting to alert of a bug I've found in the blog.
If I do some research that results in a number of results that doesn't fit a single page, the blog correctly display the first X articles, but if I want to see what comes after I have to manually write the url, because if I'm visiting:
http://www.tigsource.com/articles/search?q=dwarf+fortress
and I want to see page 2, the blog redirect me to
http://www.tigsource.com/articles/search?page=2
instead of
http://www.tigsource.com/articles/search?q=dwarf+fortress&page=2

Maybe I wrote too much, I could exlpain myself with less words but I was trying to be complete because I don't visit this forum too often nor I do have an email alert for this thread.

Ciao!
