Provide additional ranking factors

Hardcoding stickiness as a ranking factor the way you propose it probably won't be appropriate with all projects. If we want to take stickiness into account, I think we should do so through a more flexible framework for adding ranking factors. Perhaps we could integrate with the Search Ranking project (http://drupal.org/project/search_ranking).

Marked #365561: Faceted Search ignores "Always on top of lists" as duplicate.

Yes, integration with the Search Ranking module would be very useful. However, I just looked at the code used by that module, and the way the faceted search system builds the rankings, and it looks like it could be a fair amount of work to integrate the two. I would be interested in helping with the work, possibly, but it looks like a fairly daunting task to me at the moment.

Any progress on this?

I've managed to fix this with the following code:

/**
 * Implementation of hook_faceted_search_query_alter().
 */
function MYMODULE_faceted_search_query_alter($env, &$query) {
  array_unshift($query->orderby['default'], 'n.sticky DESC');
}

Apologies for dragging this up from the depths but this works perfectly for me, thought others might like to know...
