query_posts: how to show all ‘meta_value’ containing a specific word?

No need for a custom query. Since 3.1, you can use a ‘meta query’;

query_posts( array(
    'meta_query' => array(
        array( 
            'key' => 'meta_key_name',
            'value' => 'test',
            'compare' => 'LIKE'
        )
    )
) );
