Usage in another plugin

Hi,

thank you for the great plugin. From what I figure those last hours it is really nicely written and documented. Still, my wordpress insight and php skill seems not sufficient to understand it perfectly.

I use another plugin, wp-search-suggest. That did, unlike what I expected, not make use of your plugin. That is, in the suggestions, findings from custom fields could not be found.

I have a solution for that in the other problem. So all I want from you folk, is maybe some help to understand (1) why exactly my solution works and (2) how this could have been solved more elegantly, either on the search-everything side or on the wp-search-suggest side.

Thanks!

$result = array();
if ($is_query) {
	$result = array(
		'own' => array(),
		'external' => array()
	);

	$params = array(
		's' => $s
	);

	$zemanta_response = se_api(array(
		'method' => 'zemanta.suggest',
		'return_images' => 0,
		'return_rich_objects' => 0,
		'return_articles' => 1,

		'text' => $_GET['text']
	));

	if (!is_wp_error($zemanta_response) && $zemanta_response['response']['code'] == 200) {

	echo join( $results, "\n" );
}

}

echo join($results, "\n");
wp_die();
// Below this line you find the original action. It is still in place, though obviously inactive due to wp_die()

$query = new WP_Query( $query_args );

	$results = apply_filters( 'wpss_search_results', wp_list_pluck( $query->posts, 'post_title' ), $query );
