Getting CakePHP's searchable behavior results to contain deeper associations

I am trying to use CakePHP 1.3.5's searchable behavior with containable behavior to return search results for a specified model and an associated model (Article belongsTo User).

Ignoring the searchable behavior for a moment, the following call to find():

$this->Article->find('all', array(
    'conditions' => array('Article.is_published' => 1),
    'fields' => array('Article.id'),
    'contain' => array('User.name')
));

Executes this SQL query:

SELECT `Article`.`id`, `User`.`name`, `User`.`id` FROM `articles` AS `Article` LEFT JOIN `users` AS `User` ON (`Article`.`user_id` = `User`.`id`) WHERE `Article`.`is_published` = 1 

And returns the following array:

Array (
    [0] => Array (
        [Article] => Array (
            [id] => 10
        )
        [User] => Array (
            [name] => Author Name
            [id] => 7
        )
    )
    ...
)

Which is exactly what's expected. However, the following call to search():

$this->Article->search($query, array(
    'conditions' => array('Article.is_published' => 1),
    'fields' => array('Article.id'),
    'contain' => array('Article' => array('User.name'))
));

Executes this SQL query:

SELECT `Article`.`id` FROM `search_index` AS `SearchIndex` LEFT JOIN `articles` AS `Article` ON (`SearchIndex`.`model` = 'Article' AND `SearchIndex`.`association_key` = `Article`.`id`) WHERE `Article`.`is_published` = 1 AND MATCH(`SearchIndex`.`data`) AGAINST('search term' IN BOOLEAN MODE) AND `Article`.`id` IS NOT NULL 

And returns this array:

Array (
    [0] => Array (
        [Article] => Array (
            [id] => 9
        )
    )
    ...
)

Looking at the searc开发者_JAVA技巧h() method, it is returning $this->SearchIndex->find('all', $findOptions);. $findOptions contains the following:

Array (
    [conditions] => Array (
        [Article.is_published] => 1
        [0] => MATCH(SearchIndex.data) AGAINST('search term' IN BOOLEAN MODE)
    )
    [fields] => Array (
        [0] => Article.id
    )
    [contain] => Array (
        [Article] => Array (
            [0] => User.name
        )
    )
)

The association isn't getting lost along the way, because inside SearchableBehavior, $this->SearchIndex->Article->belongsTo['User'] is present and intact immediately before and after the call to find() inside the search() method.

The call to search() returns the exact same thing for all of the following values of 'contain':

array('Article' => array('User.name'))

array('Article' => array('User'))

array('Article' => array('User' => array()))

array('Article' => array('User' => array('fields' => array('User.name'))))

array('Article' => array('User' => array('fields' => array('name'))))

Am I doing something wrong? I think I'm using the same format as is instructed in the CakePHP documentation, and I haven't found anything online that suggests that you have to do something special to get search results with associated data.

I know that I could easily achieve the result that I want by just looking up the Users with additional calls to find(), but I'd like to get containable behavior to work like it's supposed to and cut down on unnecessary extra database queries.

When using containable, set the recursive option to "true"

$this->Model->Behaviors->attach("Containable",array("recursive"=>true));
