I used a somewhat dirty trick to avoid file edits

search_process_start

PHP Code:

if ($searchuser AND $vbulletin->GPC['searchthreadid'] AND !$vbulletin->GPC['query'])
{
$realuserid = $vbulletin->userinfo['userid'];
$vbulletin->userinfo['userid'] = -1;
} 


search_process_fullsearch

PHP Code:

$vbulletin->userinfo['userid'] = $realuserid; 


This way vBulletin does not find a valid searchhash and performs a new search.
