$content = elgg_list_entities(array(
    'type' => 'object',
    'subtype' => 'page_top',
    'full_view' => false,
    'no_results' => elgg_echo('pages:none'),
    
    
    'metadata_name_value_pairs' => array(
    
    array(

        'name' => 'tags',

        'value' => 'hoho',

    )),

i've tried this but it still returns all page_top entitities , i just want page_top entities that have "hoho" tag in their tags
