Let search_config work without arg(1) == 'node'

Issue Summary

When no search terms are present, search_config doesn't kick in.

I just patched search_config's form_alter in my version to let it.

The reason is that I like to expand the advanced search form when users just hit the search button (code below for anyone interested).

In your helper module's form_alter:

switch ($form_id) {
case 'search_form':
if (!arg(1)) { // if it's only /search and no keywords, expand the advanced search fieldset
$form['advanced']['#collapsed']=FALSE;
}
break;
}
