I turned on the Lucene search for all our wikis a few hours ago.
Currently everything except German, Russian, and Esperanto is running
with the English stemmer. This may not produce totally correct results
on some languages, but seems to be "good enough" to return at least some
useful results in general.
The index updater still needs a little work to fully automate; currently
I'm just running a mass update of changed pages manually every couple of
days.
