Hi. I have a problem with searching through DataObjects.
My code looks like:

function search() {
 $phrase = Director::urlParam("ID");
 $filter = "`ParentPageID` = '".Director::currentPage()->ID."' AND `Content` LIKE '%".$phrase."%'";
 $items = DataObject::get('MyObject',$filter);
 $data = array( "Results" => $items );
 return $this->customise($data)->renderWith('SearchResults');
}

And the template:

<% if Results %>
  <p>Results</p>
<% else %>
  <p>No results</p>
<% end_if %>

When the $phrase is found, everything works perfect. But when the $phrase filter doesn't match any objects, the template goes blank.
Checking $items->Count() doesn't help, it looks like the renderer doesn't work when no objects are found.

What does DataObject::get() return when the filter param doesn't match anything?
How can I make this work?
