This solution filters search strings by applying a regular expression which only matches characters from the Common and Latin Unicode scripts. Matching Latin Characters with Regular Expressions I just had my mind blown over at Stack Overflow.

It’s not possible with WP_Query directly out of the box, but by using the posts_where filter to look for a custom argument on WP_Query, it is possible to add this functionality. Assuming starts_with is the name of the argument we want to use, we can filter posts_where to add a WHERE clause limiting results to … Read more
In WP_Query() there is a ‘post__not_in’ argument where you can exclude specific post ID’s. You would create a new WP_Query inside of your search.php and use the current $query_args, then add on your ‘post__not_in’. If you wanted to make it more dynamic, you could also build in some post meta where you could do a … Read more

A GROUP BY statement can group your posts after the JOIN. For WordPress you can use the posts_groupby filter. add_filter( ‘posts_groupby’, ‘my_post_limits’ ); function my_post_limits($groupby) { global $pagenow, $wpdb; if ( is_admin() && $pagenow == ‘edit.php’ && $_GET[‘post_type’]==’listings’ && $_GET[‘s’] != ” ) { $groupby = “$wpdb->posts.ID”; } return $groupby; }
EDIT – The current version of WordPress supports relevance, so this answer is no longer accurate. There’s no concept of rank or relevance, it’s just a simple LIKE query on the post title and content: ($wpdb->posts.post_title LIKE ‘{$n}{$term}{$n}’) OR ($wpdb->posts.post_content LIKE ‘{$n}{$term}{$n}’) You can use the posts_search filter to modify or completely replace the search … Read more
