Empty results

When a glossary search returns no results the page is blank. It would be much better if we say the search result was empty. I did a quick thing in the glossary_search_results function that also places the search form on the page.

if (db_num_rows($result) == 0) {
    return '<p>Your search returned no results</p>' . drupal_get_form('glossary_search_form');
}
