Interesting. I might have found a bug, but I can’t confirm yet. Could you please open up the wp-content/plugins/ajax-search-pro/includes/search_content.class.php file and go to line 302, where you should see this code:
[code]CONCAT(‘–‘, GROUP_CONCAT(DISTINCT $wpdb->terms.term_id SEPARATOR ‘—-‘), ‘–‘) as ttid,[/code]
Replace that line with this:
[code](SELECT DISTINCT CONCAT(‘–‘, GROUP_CONCAT( $wpdb->term_taxonomy.term_id SEPARATOR ‘—-‘ ), ‘–‘) FROM $wpdb->term_taxonomy
LEFT JOIN $wpdb->term_relationships ON $wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id
WHERE ($wpdb->term_relationships.object_id = $wpdb->posts.ID) ) as ttid,[/code]
That will possibly solve this issue, at least I hope so.
