[TYPO3] Extension for PDF upload and indexing

[Rolf Kutz]

Hello,

for a project I would like to have a page where
fe-users can upload PDF files along with some
additional information (like abstract, author,
etc.). The pdf files should be indexed, searchable
and viewable along with the additional
information. Is there an extension I could use for
that? Any other aproach I could use? 

regards, Rolf
