For the PDFs, you might look into using XPDF (http://www.foolabs.com/xpdf/). You'd have to compile xpdf for the environment it will be running on, but then you could just use system() or any similar function to read the PDF. At that point you can use the code below. For a similar example of how to do this, take a look at the "PDF Indexer" extension for Joomla!.
I'm not really sure about docx; I've never had to work with that format. Hopefully this helps get you halfway there, though.
