[Plugin: WP Search] Index Taxonomies?

I need and hack to index also all term of any taxonomies of each post.
It works ok, but search excerpt display all terms…

I patched Phplucene.php file on drivers subfolder, near

ADD:
$addc=””; $taxonomies=get_taxonomies();
foreach ($taxonomies as $taxonomy ) {
$terms=wp_get_object_terms( $post->ID, $taxonomy, null);
foreach ($terms as $term) {
$dr= (array) $term;
$addc .= $dr[“name”].” “;
};
};
$post->post_content .= $addc;

BEFORE:

$comments = ($index_comments ? $this->_getCommentsAsString($post->ID) : FALSE);
$categories = ($index_categories ? $this->_getCategoriesAsStrings($post->ID) : FALSE);
# WPSearch_Log::add(‘debug’, “Indexing post: $post->ID”);
$index->addDocument($this->_createLuceneDocument($post, $categories, $comments));
