TYPO3 Core

Can you please add a screenshot?
I've tried this with 4.5 and 4.6 on pages properties and the "general record storage" - however the search in the element browser worked for me, see

I've discovered this in a TYPO3 installation of one of my customers using TYPO3 4.6.5. The customer is using seminars. I was able to reproduce the behavior on my own TYPO3 installation with 4.6.5 and seminars. I've added an organizer with my name and tried to search for it. The search result is empty. It is working with TYPO3 version 4.5.

The corresponding TCA in seminars looks like this where $selectType is set to "group":

        'organizers' => array(
            'exclude' => 0,
            'label' => 'LLL:EXT:seminars/locallang_db.xml:tx_seminars_seminars.organizers',
            'config' => array(
                'type' => $selectType,
                'internal_type' => 'db',
                'allowed' => 'tx_seminars_organizers',
                'foreign_table' => 'tx_seminars_organizers',
                'foreign_table_where' => tx_seminars_tableRelations(
                    'tx_seminars_organizers'
                ),
                'size' => 5,
                'minitems' => 1,
                'maxitems' => 999,
                'MM' => 'tx_seminars_seminars_organizers_mm',
                'wizards' => tx_seminars_tableReplace($tempWizard, 'tx_seminars_organizers'),
            ),
        ),
