When using a view with exposed filters, if the exposed filter is empty, by default views renders the view with all results displayed. To make an empty view instead :

• Add an argument "Global: Null"
• Action to take if argument is not present: Provide default argument
• Default argument type: Fixed entry
• Default argument: let it blank
• Validator: PHP code
• PHP validate code:
  if (!empty($view->exposed_input) && count($view->exposed_input) == 1 && isset($view->exposed_input['destination'])) {
return FALSE;
}
return (!empty($view->exposed_input));
• Action to take if argument does not validate: Display empty text (if you want the view to be rendered)

And voilà !
