TYPO3 Core

This issue is on the search function of the list module in the TYPO3 BE. Not the live search in the BE, not about FE searches.

Steps to reproduce

• TYPO3 8.7
• Log into the BE as an admin
• Activate the "Indexed Search" extension
• Switch to the list module
• Create an indexed search configuration record (anywhere). Save and close.
• Click the search icon in the header of the list view (Not the live search at the top right)
• Enter a random search word like "aPPnmtdkRE"

Expected result: No items should be found at all
Actual result: The indexed search configuration will be found (allthough it does not contain 'aPPnmtdkRE'.

typo3/sysext/recordlist/Classes/RecordList/AbstractDatabaseRecordList.php:922

public function makeSearchString($table, $currentPid = -1)
        …
        $searchableFields = $this->getSearchFields($table);
        if (empty($searchableFields)) {
            return '';
        }

If getSearchFields returns [], the searchString constraint is returned as ''. This results to no search constraint for the given table at all. Instead we should either

• Search all fields of the given table
• Return false, to remove the table from the search results entirely.
