search engine failure

[jeffbert]

I was looking for "C0untd0wn cl0ck" but the thing returned "Sorry - no matches. Please try some different terms." But that very term is exactly the thread's name: C0untdown cl0ck
Note that to retain the error, I have used '0' rather than 'o'.

However, after posting a link to that very thread, the simple search finds the thread in which the link is posted, but still fails to find the thread by that name. Moreover, the advanced search still returns a failure.
Since I have initially used the term in another thread, it finds that thread, even though I have since edited and removed the term, but still fails to find the thread by that name.
Videos about that Astro animatronic showed on 2003?

I have tons of problems with the search engine since the forum was upgraded to vBulletin last year. I thought I had noticed that the older threads were the problem. The newer seems fine, but I never tested it so I'm not completely sure that what I'm saying is true.

I'm wondering if there isn't some kind of search index to update. I have upgraded a forum recently (phpBB 2.x -> 3.x), and the search wouldn't work until I rebuild the search index burried somewhere in the admin panels It was working for new posts before the update though.

Makes sense!

We can always count on you when we have technical issues!
