Heavens Amin it's so long since I've looked at mu43 that I can't remember!
I think I just had a moment of pre-senile confusion and thought SC used the same as the APUG search.
I've never found the standard vBulletin search very useful on any forum, and sometimes resort to using "site:" prefix on google to track stuff down.
I've had a quick look at mu43 and it seems fine - though are results limited to 10 pages?
