	 * We work in either of two modes. The default is to queue inserts and process
	 * them later. This allows good performance for the user.
	 * In this mode we don't actually do any indexing. We just write a record to the
	 * queue table,which is indexqueue.
	 * Later the cron job will scan the table and actually index the items.
	 * If the admin flag $vbulletin->config['search']['immediatewrites'] is set to 1
	 * then we process them immediately
	 * Normally we will be called static, i.e. "vb_Search_Indexcontroller_Queue::index();
