TYPO3 Core

Hi, i had the problem that the indexed_search doesn't find any meta keywords on the search results.
Then i debugged this part:
https://github.com/TYPO3/typo3/blob/master/typo3/sysext/indexed_search/Classes/Indexer.php#L400-L415

 if ($this->conf['index_metatags']) {
            $meta = [];
            $i = 0;
            while ($this->embracingTags($headPart, 'meta', $dummy, $headPart, $meta[$i])) {
                $i++;
            }

            // @todo The code below stops at first unset tag. Is that correct?
            for ($i = 0; isset($meta[$i]); $i++) {
                // decode HTML entities, meta tag content needs to be encoded later
                $meta[$i] = GeneralUtility::get_tag_attributes($meta[$i], true);
                if (stripos($meta[$i]['name'], 'keywords') !== false) {
                    $contentArr['keywords'] .= ',' . $this->addSpacesToKeywordList($meta[$i]['content']);

                }
                if (stripos($meta[$i]['name'], 'description') !== false) {
                    $contentArr['description'] .= ',' . $meta[$i]['content'];
                }
            }

The problem is, that the while only found the hreflang meta tag an then stop working.
Maybe you can change the part like this, with the new MetaTagApi ... it worked for me :)

        // get keywords and description metatags
        if ($this->conf['index_metatags']) {
            // Get Keywords
            $metaTagManager = GeneralUtility::makeInstance(MetaTagManagerRegistry::class)->getManagerForProperty('keywords');
            $keywords = $metaTagManager->getProperty('keywords');
            if(!empty($keywords[0]['content'])) $contentArr['keywords'] .= ',' . $this->addSpacesToKeywordList($keywords[0]['content']);
            // Get Description
            $metaTagManager = GeneralUtility::makeInstance(MetaTagManagerRegistry::class)->getManagerForProperty('description');
            $pageDescription = $metaTagManager->getProperty('description');
            if(!empty($pageDescription[0]['content'])) $contentArr['description'] .= ',' . $pageDescription[0]['content'];
        }
