Hi!
I could not enter with the credentials, perhaps my IP is restricted after all.
But I think I might found a quick solution for your request.
0. Turn off fulltext search if you are using it: http://i.imgur.com/1BcUDJ5.png
1. Open up the plugins/ajax-search-pro/includes/search_content.class.php file and go to line 52, where you should see this:
/*----------------------- Title query ---------------------------*/
if ($options['set_intitle']) {
$words = $options['set_exactonly']==1?$s:$_si;
$parts[] = "(lower($wpdb->posts.post_title) REGEXP '$words')";
$relevance_parts[] = "(case when
(lower($wpdb->posts.post_title) REGEXP '$words')
then $searchData[titleweight] else 0 end)";
$relevance_parts[] = "(case when
(lower($wpdb->posts.post_title) REGEXP '$s')
then $searchData[etitleweight] else 0 end)";
}
/*---------------------------------------------------------------*/
2. Replace that code with this:
/*----------------------- Title query ---------------------------*/
if ($options['set_intitle']) {
$words = $options['set_exactonly']==1?$s:$_si;
$parts[] = "(lower($wpdb->posts.post_title) REGEXP '$words')";
$relevance_parts[] = "(case when
(lower($wpdb->posts.post_title) REGEXP '$words')
then $searchData[titleweight] else 0 end)";
/*$relevance_parts[] = "(case when
(lower($wpdb->posts.post_title) REGEXP '$s')
then $searchData[etitleweight] else 0 end)"; */
// The first word relevance is higher
if (count($_s)>1)
$relevance_parts[] = "(case when
(lower($wpdb->posts.post_title) REGEXP '".$_s[0]."')
then $searchData[etitleweight] else 0 end)";
}
/*---------------------------------------------------------------*/
This modification will give the first search word higher priority, thus the order of the results will change.
