How to Find Records using MySQL Match Against Query in CakePHP

To use MySQL Match Against Query in CakePHP:

$needle = 'Search String';

$conditions = array( 
 "MATCH(Post.title) 
  AGAINST('$needle' IN BOOLEAN MODE)" 
  );
 $matches = $this->Post->find('all', array('conditions' => $conditions));

It does not need any explanation. I hope.
