METHODS

new

  my $indexdb = Search::InvertedIndex::DB::Mysql->new(
                   -db_name    => $dbname,
                   -username   => $dbuser,
                   -password   => $dbpass,
		   -hostname   => '',
                   -table_name => 'siindex',
                   -lock_mode  => 'EX' );
  my $search = CGI::Wiki::Search::SII->new( indexdb => $indexdb );

Takes only one parameter, which is mandatory. indexdb must be a Search::InvertedIndex::DB::* object.

search_nodes

# Find all the nodes which contain the word 'expert'.
my %results = $search->search_nodes('expert');

Returns a (possibly empty) hash whose keys are the node names and whose values are the scores in some kind of relevance-scoring system I haven't entirely come up with yet. For OR searches, this could initially be the number of terms that appear in the node, perhaps.

Defaults to AND searches (if $and_or is not supplied, or is anything other than OR or or).

index_node

$search->index_node($node);

Indexes or reindexes the given node in the Search::InvertedIndex indexes.

delete_node

$search->delete_node($node);

Removes the given node from the search indexes. NOTE: It's up to you to make sure the node is removed from the backend store. Croaks on error.

supports_phrase_searches

if ( $search->supports_phrase_searches ) {
    return $search->search_nodes( '"fox in socks"' );
}

Returns true if this search backend supports phrase searching, and false otherwise.
