I've activated the Lucene search now on the following wikis:
enwiki enwiktionary enwikiquote enwikibooks enwikinews
dewiki dewiktionary dewikiquote dewikibooks dewikinews dewikiversity
eowiki eowiktionary eowikiquote eowikibooks
ruwiki ruwiktionary ruwikibooks ruwikiquote
sourceswiki metawiki sep11wiki foundationwiki commonswiki specieswiki
grantswiki
Will add the rest shortly, though probably with non-ideal configurations.
I've added Image: and Category: namespaces to the default search set on
Commons.
