You can do this by simply accessing it like:

'columns'=>[
   'country.columnName',
]);
In model override attributes() function:

public function attributes()
{
    // add related fields to searchable attributes
    return array_merge(parent::attributes(), ['country.columnName']);
}
Add it to rules:

public function rules()
{
     return [
         [['country.columnName'], 'safe'],
            // ... more stuff here
     ];
}
And in search() method, add this to your Query:

$query->andFilterWhere(['LIKE', 'country.columnName', $this->getAttribute('country.columnName')]);
```
