PortalQueryParameters Question

[MattSheehan]

I have working code which allows users to login and see their published items:

protected function portalService_loadHandler(event:PortalEvent):void
{    
   var queryString:String = "owner:" + event.target.user.username;
    
   lastQueryString = queryString;
   var queryParameters:PortalQueryParameters = defaultQueryParameters.clone();
   //Load 100 features
   queryParameters.withLimit(100);
   queryParameters.addQueryCondition(queryString);
   portalService.queryItems(queryParameters);
}

I'd like them also to see all shared items which are in membership groups. Wondering how I might change the above code?

Thanks
