Full text Search block does not work outside of CiviCRM

I think the reason is because the javascript variable cj is not loaded onto the page. The usually happens when civicrm_add_jquery() is called, but this does not happen unless you are in CiviCRM or on a CiviCRM form. hook_block should also force that to be called if the javascript is required for the block in question to function, whcih seems to be the case for the Full Text Search block.
