A better solution would be to address these in the templates directly. See modules/search/search-result.tpl.php and template_preprocess_search_result() in modules/search/search.pages.inc

Copy the tpl into your theme directory and make changes there or use MYTHEME_preprocess_search_result() in your theme's template.php file. After adding the file or the function, clear cache so that the theme registry will utilize these. See http://drupal.org/node/223430 for more information.
