Faceted Search

The search results plugin shows nothing at all when it tries to display results containing chr(11) (ascii-tab). You may argue whether these codes should be there at all (probably inserted by some editor using cut and paste from another site or program), but since TYPO3 doesn't remove them ke_search shouldn't fail when they occur.

I found them in title and content fields of news records.

I resolved the issue by filtering in the indexer, class.tx_kesearch_indexer.php starting from line 394:

    public function prepareRecordForInsert($fieldValues) {
        $addQueryPartFor = $this->getQueryPartForAdditionalFields($fieldValues);

        $removeCharacters = array(chr(11));
        $queryArray = array();
        $queryArray['set'] = 'SET
            @pid = ' . $fieldValues['pid'] . ',
            @title = ' . str_replace($removeCharacters, '', $fieldValues['title']) . ',
            @type = ' . $fieldValues['type'] . ',
            @targetpid = ' . $fieldValues['targetpid'] . ',
            @content = ' . str_replace($removeCharacters, '', $fieldValues['content']) . ',
            @tags = ' . $fieldValues['tags'] . ',
            @params = ' . $fieldValues['params'] . ',
            @abstract = ' . str_replace($removeCharacters, '', $fieldValues['abstract']) . ',
            @language = ' . $fieldValues['language'] . ',
            @starttime = ' . $fieldValues['starttime'] . ',
            @endtime = ' . $fieldValues['endtime'] . ',
            @fe_group = ' . $fieldValues['fe_group'] . ',
            @tstamp = ' . $fieldValues['tstamp'] . ',
            @crdate = ' . $fieldValues['crdate'] . $addQueryPartFor['set'] . '
        ;';

Probably the issue could also be solved in the output rendering part but I didn't look into that.
