[Edit]With virtual wiki

When search "update" in en wiki, the result is not empty, but in zh wiki (a virtual wiki I created), the search doesn't find anything. Is there anything wrong? What & how should I do?

Previously, I found this problem, but then after search some English words, it works, then it works for all. But this time, it works only for en wiki (also good with Chinese charaters), but not in zh wiki (even not with English words). --jack 20-Jul-2010 11:03 PDT
