Just did a fresh install of Fireboard 1.0.3 with Joomla 1.0.13. My first time trying it out, actually. I like it and want to use it, so I'm hoping my info here will help make it even better...
Looks to me like the forum search is returning results only for top-level forums, and not for child forums. For example, in the support forums you're now using, take a look at this thread:
c'est mon post a moi
www.bestofjoomla.com/component/option,co...iew/id,922/catid,30/
Notice that the first post in this thread contains the word "bonjour". If you search for this word, you won't get any results back, (even though I just repeated the word in this paragraph), because this thread is a child forum. Also, the word will not be found in the "c'est mon post a moi" thread, since it is also a child forum.
Try posting something in a top-level forum with "bonjour" in it. It should show up in search results. Perhaps I'll do that myself, and edit this post with that link... Be right back.

[edit] Yes, the results show up in my other top-level forum post, but not here. The bug is repeatable on these forums.
