Symfony2应用程序，MongoDB:统计所有符合条件的记录

在我的控制器中，我获取有限数量的对象（用于分页），如下所示：

    $dm   = $this->get('doctrine_mongodb');
    $repo = $dm->getRepository('AcmeMyBundle:MyDocument');

    $criteria = array(
        'field1'    => 'value1',
        'field1'    => 'value1',
    );

    $logs = $repo->findBy(
        $criteria,                      /* criteria */
        array($field => $direction),    /* sort */
        $limit,                         /* limit */
        (($page-1)*$limit)?:null        /* skip */
    );

$count = $repo->createQueryBuilder('MyDocument')
    ->count()->getQuery()->execute();

    $countQuery = $repo
        ->createQueryBuilder('MyDocument')
        ->requireIndexes(false)
        ;

    foreach(array_filter($criteria) as $field=>$value){
        $countQuery->field($field)->equals($value);
    }

    $count = $countQuery->count()->getQuery()->execute();

现在，我想获得满足

$标准的记录总数

我试着这样数数：

    $dm   = $this->get('doctrine_mongodb');
    $repo = $dm->getRepository('AcmeMyBundle:MyDocument');

    $criteria = array(
        'field1'    => 'value1',
        'field1'    => 'value1',
    );

    $logs = $repo->findBy(
        $criteria,                      /* criteria */
        array($field => $direction),    /* sort */
        $limit,                         /* limit */
        (($page-1)*$limit)?:null        /* skip */
    );

$count = $repo->createQueryBuilder('MyDocument')
    ->count()->getQuery()->execute();

    $countQuery = $repo
        ->createQueryBuilder('MyDocument')
        ->requireIndexes(false)
        ;

    foreach(array_filter($criteria) as $field=>$value){
        $countQuery->field($field)->equals($value);
    }

    $count = $countQuery->count()->getQuery()->execute();

但它统计收集的所有记录。如何将
$criteria
应用于该计数查询

我需要将结果作为本机
MongoDB
db.MyDocument.find（{'field2'：'value1'，'field2'：'value2}）。count（）

这样做：

    $dm   = $this->get('doctrine_mongodb');
    $repo = $dm->getRepository('AcmeMyBundle:MyDocument');

    $criteria = array(
        'field1'    => 'value1',
        'field1'    => 'value1',
    );

    $logs = $repo->findBy(
        $criteria,                      /* criteria */
        array($field => $direction),    /* sort */
        $limit,                         /* limit */
        (($page-1)*$limit)?:null        /* skip */
    );

$count = $repo->createQueryBuilder('MyDocument')
    ->count()->getQuery()->execute();

    $countQuery = $repo
        ->createQueryBuilder('MyDocument')
        ->requireIndexes(false)
        ;

    foreach(array_filter($criteria) as $field=>$value){
        $countQuery->field($field)->equals($value);
    }

    $count = $countQuery->count()->getQuery()->execute();
