 Maximum flexibility is definitely needed. With the patch you can search
 custom meta data, terms or data stored in other custom post types (by
 joining tables with the `posts_join_paged` filter), or even do more
 complicated lookups (by using the `posts_fields` filter and nesting a
 SELECT).

 One obvious real-world scenario that the filter would make possible
 (together with a JOIN) would be being able to extend the search at `wp-
 admin/edit.php` to include tags.
