Collection filtering

I'm trying to filter a collection by one group of 'match'=>'or' filters, as well as another filter:

perch_collection('Blog Posts',array(
          'template' => 'blog/posts/post_in_list.html',
          'count'=>6,
          'sort'=>'postDateTime',
          'sort-order'=>'DESC',
      'filter'=>array(
        array(
          'filter'=>array(
            array(
              'filter'=>'postTitle',
              'match'=>'contains',
              'value'=>perch_get('q')
            ),
            array(
              'filter'=>'excerpt',
              'match'=>'contains',
              'value'=>perch_get('q')
            ),
            array(
              'filter'=>'postDescHTML',
              'match'=>'contains',
              'value'=>perch_get('q')
            ),
          ),
          'match'=>'or',
        ),
        array(
          'filter'=>'postDateTime',
          'match'=>'lte',
          'value'=>date('Y-m-d H:i:s')
        ),
      ),
    ));

Which is giving me the following error:

Notice: Undefined index: value in /var/www/public/ifstudies.dev/ifs-admin/core/runway/apps/content/PerchContent_Runway.class.php on line 203

Am I doing something wrong? Is this even possible? Thanks for the help.
