Carlo Bifulco created a program called PdfSearch do just what you want.
Its homepage is at:

    http://pdfsearch.sourceforge.net/

I have not tried the latest version, but I remember the project because
Carlo uses my indexer.py module as part of his project.

In terms of my indexer.py module, I wrote an article about full text
indexing at:

    http://gnosis.cx/publish/programming/charming_python_15.html

This was extended to cover XPATH indexing of XML documents in:

    http://gnosis.cx/publish/programming/xml_matters_10.html

The latter isn't your interest, but in concept it is somewhat similar to
Carlo's extension.
