I'm trying it using PHP api, but no success

My ES query :  
$aFindCountries = array();  
$aFindCountries['index'] = 'my\_table';  
$aFindCountries['type'] = 'data';  
$aFindCountries['body'] = array(

```
'size' => 0,
'query' => array(
    'filtered' => array(
        'query' => array(
            'query_string' => array(
                'query' => '*',
                'analyze_wildcard' => true
            )

        )
    )
),
'aggs' => array(
    'Distinct' => array(
        'terms' => array(
            'field' => 'user_country',
            'size' => 155,
            'order' => 'desc'
        )
    )
),

```

);

I want to find the distinct country names from my\_table;  
Thanks
