TYPO3 Core

There used to be a feature in indexed search where while indexing the document title would be added to a pdf if there was any, this feature now seems to have vanished completely.

The feature can be implemented in 3 lines so I think it would be a shame to not use it (also since it is used in other file types this completely makes sense):

File: indexed_search/Class/FileContentParser.php:477ff

...
if(strlen($pdfInfo['title'])) {
$contentArr['title'] = $pdfInfo['title'];
} else { // I consider this part rather optional, so maybe you can leave this out
$contentArr['title'] = explode(chr(10), $contentArr['body'])[0]; // get the first line as document title
}
