Limit filter operators

I don't think there is an option to sort the exposed operators.

You can do it with a custom module using hook_form_alter().

Example:

function module_name_form_alter(&$form, &$form_state, $form_id) {

  if ($form_id == 'views_exposed_form' && $form_state['view']->name == 'view_name') {
    unset($form['field_name_filter_op']['#options']['empty']);
    unset($form['field_name_filter_op']['#options']['not empty']);
  }

}

You can find the form details using "dpm()" from devel module.

• dpm($form_id);
• dpm($form);
• dpm($form_state);
