How can I exclude a Wordpress post type from being indexed?

Is there a way to prevent specific post types from being indexed by the Swiftype WordPress plug-in?

This can be accomplished with version 1.1.34 or higher of the Swiftype Plug-in.

Add the following code to your WordPress theme’s functions.php and then update the values within the **$excluded_post_types** array with your relevant post types.

function exclude_swiftype_documents( $document, $post ) {
    $excluded_post_types = array('VALUE1', 'VALUE2');
    $post_type = get_post_type( $post );

    if ( in_array( $post_type, $excluded_post_types ) ) {
    	return NULL;

    return $document;

add_filter( 'swiftype_document_builder', 'exclude_swiftype_documents', 10, 2 );
