get_users meta_query with multiple custom fields

Hello
I am working on one filed user search.
Basicly I need one field (like default WordPress search) that will search in users for that search string.

I have made a few custom fields:
city (string)
country (drop-down list of pre-defined countries)
user_description (I have removed default”bio” textarea and made new one.)
telephone
mobile phone

So I would like to search in these custom fields for provided search string.
I was working on meta_query but either I get a list of all users or none so ever.

I was working on this code:

$search_word = "eng";
    $args = array(
		'role' => 'contributor',
        'meta_query'   => array(
                'relation' => 'OR',

            array(
                'key' => 'country',
                'value' => $search_word,
                'compare' => 'LIKE'
            ),
            array(
                'key' => 'city',
                'value' =>  $search_word,
                'compare' => 'LIKE'
            )

       )
    );
$users = get_users($args);
foreach($users as $user) {
if ( $user->city ) { echo $user->city; };
}

So I need to search in multiple custom fields where in ANY of these fields has a value LIKE the search string.

Can someone give me a hint what I did wrong?

And another question:
Can I “order” the results by custom field or only on default fields?

Thank you all for your help.

Matic
