I wanted to hunt up the old wilderness thread for a reference link, and I knew that Geoff the Slug was mentioned in it, so I used the local search box and entered "Geoff the Slug" (quotes included). The search only returned two hits, both for NTJedi's terrain types thread.
But when I ran the search from Google proper and added the site:forums.elementalgame.com delimiter, I got four hits for four different threads, including the one I wanted to find.
That seems a little broken to me, but I'm just an end user...
