ItemID Search Broken?

I have a script that searches for an item based on the Name/Number (we use 5 digit #s). Today I noticed the script no longer works correctly. I am using the 2011.2 API. My code is as follows:

------
q = new nScomplexObject("SearchStringField");
$q->setFields(array("searchValue" => $item,
                    "operator" => "is"));

$search = new nsComplexObject("ItemSearchBasic");
$search->setFields(array("itemId" => $q));

$myNSclient->setSearchPreferences(false, 10);
print_r($search);
$searchResponse = $myNSclient->search($search);
print_r($searchResponse);
------

I coded a version using the 2012.2 API and it returns similar results.
------
$service = new NetSuiteService();
$service->setSearchPreferences(false, 20);

$itemId = new SearchStringField();
