my %wombat_nodes = $search->search_nodes("wombat");
Provides search-related methods for Wiki::Toolkit.

my $search = Wiki::Toolkit::Search::DBIxFTS->new( dbh => $dbh );
You must supply a handle to a database that has the
DBIx::FullTextSearch indexes already set up. (Currently though there's
no checking that what you supply is even a database handle at all, let
alone one that is compatible with DBIx::FullTextSearch.)
