Search Filter Problem

Hi All,

I'm having a problem with a search filter that i create in a suitelet. I'm basically creating a dynamic search for specific items. For simplicity here, I've hard coded these filter values. I'm trying to retrieve multiple rows of item data based on the filter. I can retrieve a single value, no problem. The problem is when i try to use an operator such as "contains" or "anyof". In the code snippet below, i use "anyof" and get the error - UNEXPECTED_ERROR. When i use "contains", i only get one row - I'm expecting 2.

 function getComboItem(request, response)  {   var itemIds = new Array();   var filters = new Array();     itemIds[0] = 'DS-CH40';   itemIds[1] = 'DS-CH30';     filters[0] = new nlobjSearchFilter ('itemid', null, 'anyof', itemIds, null );     var columns = new Array();   columns[0] = new nlobjSearchColumn('itemid');   columns[1] = new nlobjSearchColumn('storedisplayname');   columns[2] = new nlobjSearchColumn('price');   columns[3] = new nlobjSearchColumn('urlcomponent');   columns[4] = new nlobjSearchColumn('custitem_drilldownlargeimage1');   columns[5] = new nlobjSearchColumn('custitem_drilldownthumb1');   columns[6] = new nlobjSearchColumn('internalid');     var searchResults = nlapiSearchRecord('item', null, filters, columns);  }
