ApacheSolr not creating proper RSS feeds

As an update I think that if you install ApacheSolr then hte path is actually http://mysite/apachesolr_search/ but otherwise it defaults to the path specified above

Sorry I got all muddled up in my original message kiam.

What I meant was that I suspect if you don't install Views3 then the default ApacheSolr is the path http://mysite/apache_solr/* rather than http:///apachesolr_sort/*

On the site that I am working on we aren't actually changing the ApacheSolr path this is what is used by the latest ApacheSolr module (w/o Views3). An example of this can be found here - http://library.ole.org/search/apache_solr/test

I'm not sure I have a solution here either then testing for both cases?

I also noticed that in your opensearch you are only checking for filters, but not checking for sort by criteria. This could be a really awesome addition to your great module.

Your original code:

/**
 * Implementation of hook_form_alter
 */
function opensearch_form_alter(&$form, $form_state, $form_id) {
  // Only checking for filters attribute
  if ($form_id == 'search_form' && (arg(2) || (arg(1) == 'apachesolr_search' && $_GET['filters']))) {
    // for pagination etc.
    $get = drupal_query_string_encode($_GET, array('q'));
    $form['basic']['inline']['rss'] = array('#type' => 'markup', '#value' => 
theme('xml_icon', url('opensearch/'. arg(1) .'/'. urlencode(search_get_keys()), array('query' => trim($get)?$get:NULL))));
  }
}

My suggested modification:

/**
 * Implementation of hook_form_alter
 *
 * Overriding opensearch behaviour to A) allow RSS on main page B) to change icon being output
 */
function ole_general_form_alter(&$form, $form_state, $form_id) {
    // Checking for any q value (i.e. filter, solrsort, etc)
    $get = drupal_query_string_encode($_GET, array('q'));
    if ($form_id == 'search_form' && (arg(2) || ($search == 'apachesolr_search' && !empty($get)))) {
      // for pagination etc.
      $get = drupal_query_string_encode($_GET, array('q'));
      $form['basic']['inline']['rss'] = array('#type' => 'markup', '#value' => theme('xml_icon', url('opensearch/'. arg(1) .'/'. urlencode(search_get_keys()), array('query' => trim($get)?$get:NULL))));
  }
}

Note: I simply grabbed all the q values and determined if that is empty or not. If it isn't empty then apachesolr must be taking on either a filter, sort, etc. Not entirely sure whether this is the best code to handle this situation.

Just updating the status sorry
