TYPO3 ke_search

Question

I want ke_search to index metadata of pages like 'author' or 'description' (and add it to "content"). I have a class "AdditionalFields" with 'registerAdditionalFields':

$additionalFields[] = 'author';

and then this:

public function modifyPagesIndexEntry($uid, &$pageContent, &$tags, $cachedPageRecords, &$additionalFields)
    {
        if (isset($cachedPageRecords[0][$uid]['author'])
            && $cachedPageRecords[0][$uid]['author'] > 0
        ) {
            $additionalFields['content'] .= $cachedPageRecords[0][$uid]['author'];
        }
    }

but with this the "content" (in the DB) ist replaced by the 'author'. Any ideas?

The easiest way to achive what you want is to implement following hook.

EXT:your_extension/Classes/Hooks/KeSearchPageIndexerHook.php

<?php
namespace VENDOR\YourExtension\Hooks;

use TYPO3\CMS\Core\Database\ConnectionPool;
use TYPO3\CMS\Core\Utility\GeneralUtility;

class KeSearchPageIndexerHook
{
    public function modifyPagesIndexEntry(
        $uid,
        &$pageContent,
        $tags,
        $cachedPageRecords,
        $additionalFields,
        $indexerConfig,
        $indexEntryDefaultValues,
        $pageIndexerClass
    )
    {
        $table = 'pages';
        $querybuilderProductgroup = GeneralUtility::makeInstance(ConnectionPool::class)
            ->getConnectionForTable($table)
            ->createQueryBuilder();

        $author = $querybuilderProductgroup
            ->select('author')
            ->from($table)
            ->where(
                $querybuilderProductgroup->expr()->eq('uid', $uid)
            )
            ->execute()
            ->fetchOne();

        if($author != '')
        {
            // Be aware that $pageContent is an array with all localizations of the indexed content.
            // $pageContent[0] is the base-language. Just in case you have a multi-language setup.
            $pageContent[0] = "Author: $author " . $pageContent[0];
        }

    }

}

And then register the hook in the localconf. EXT:your_extension/ext_localconf.php

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['ke_search']['modifyPagesIndexEntry'][] =
    \VENDOR\YourExtension\Hooks\KeSearchPageIndexerHook::class;

That should do the job.
