keyword search shows no results because global vars of pager_query()

Hi folks,

First time around here and I didn't find anything similar in other posts, so if it's not new, sorry. I was getting very frustrated because I got the "Your search yielded no results" message with FS all the time, although there were results with the core search module.

I looked a bit inside and it seems like there's a problem with the global vars $pager_total_items, $pager_total and $pager_page_array between the moment the function pager_query() is called in faceted_search.inc and the moment the function theme_faceted_search_ui_stage_results() is called in faceted_search_ui.inc [line 71 -> return theme('faceted_search_ui_search_page', $results, 'node'); ]. The globals get rewriten, probably by some other process or module (I don't know). The $pager_total_items variable returns always the same array: (0=>0). Thing is, I solved the problem creating new globals in the function load_results() in faceted_search.inc [line 1192] and passed those to the respective theme function. Now it works, but this is probably not the proper way to solve this and I don't know if this happens only in my drupal installation. Maybe someone has a better insight of what's wrong. I wouldn't like to hack around like this everytime I update FS, so I ask for your help...

So here's what I've done to solve it for now:

I changed function load_results() in faceted_search.inc [line 1192] into this:

   function load_results($limit = 10) {
  	global $pager_page_array, $pager_total, $pager_total_items, $fs_pager_page_array, $fs_pager_total, $fs_pager_total_items;
    $found_items = array();
    if ($this->_results_count) {
      $result = pager_query("SELECT * FROM ". $this->_results_table, $limit, 0, 'SELECT '. $this->_results_count);
      $fs_pager_total = $pager_total;
      $fs_pager_total_items = $pager_total_items;
      $fs_pager_page_array = $pager_page_array; 
      while ($item = db_fetch_object($result)) {
        $found_items[] = $item;
      }
    }
    return $found_items;
  }

and function theme_faceted_search_ui_stage_results() in faceted_search_ui.module [line 1416] into this

function theme_faceted_search_ui_stage_results($results, $style) {
  global $fs_pager_total, $fs_pager_total_items, $fs_pager_page_array;
  if ($fs_pager_total_items[0] > 0) {
    $limit = $style->get_limit();
    $from = $fs_pager_page_array[0] * $limit + 1;
    $to = min(($fs_pager_page_array[0] + 1) * $limit, $fs_pager_total_items[0]);
    $total = $fs_pager_total_items[0];
    ...

cheers,

rodrigo
