Hi Keith
The filter is sf_apply_filter_sort_post__in
$post__in = apply_filters('sf_apply_filter_sort_post__in', $this->query_args['post__in'], $this->query_args, $this->sfid);
Which takes an array of post IDs (the results S&F has found) and must return those posts.
You’ll then have to disable sorting and sort by post__in
in the query (actually, you might be able to leave this set as “default” ordreing in your search form options), you can use the sf_edit_query_args
filter to do this.
If you’re going to follow the link above exactly, the JOIN
option might work for you anyway, but there’s two potential approaches for you to try.
Thanks
