+ will now need to install xapian-omega, and the [[cpan Search::Xapian]],
+ [[cpan HTML::Scrubber]], and [[cpan Digest::SHA1]] perl modules. Ie,
+ `apt-get install xapian-omega libsearch-xapian-perl libhtml-scrubber-perl libdigest-sha1-perl`

+ Also, wikis that use the search plugin will need to be rebuilt,
