To be honest, this isn't actually that crucial of a fix. Because the main site search was down for so long, I just got used to manually typing in smogon.com/bw/pokemon/name, but now the main site search is back, allowing you to search for analyses and such with it. You just can't make the search with Xenforo's search function.
Click the Smogon crest thing at the top of the page, and it should take you back to the home page. There you can search for analyses, even for Mew and Muk!
The Xenforo search only searches the forums anyways, so you wouldn't be able to get analyses through it. You'd only be able to get things such as discussion threads and usage statistics, a la:
Still, it should probably allow you to search for Pokemon, but I don't see it being a high priority.
