Search result excluding other language /en

Hi,

I know you can exclude a search result from the menu structure like /en. But how to exclude it from the search result?

<?php
$query = perch_get('q');
perch_content_search($query, array(
    'count' => 12,
    'from-path'=>'/', <= how to make it only search on the first level of the menu structure
    'excerpt-chars'=>300
));
?>

Thanks in advance

Is Perch CMS dead? I just bought a subscription, Is it a mistake...Hope not.
