Hi Hans
It is not easy - but possible.
Windows search service uses iFilter to index the various document types, and one specifically for PDFs. You can find a iFilter for PDF that supports OCR to have it index PDFs with text embedded as images. An example: http://www.abbyyeu.com/rs/en:ifilter
If you get that up and running, you do not need any changed in DW search module.
That requires that filter to be installed on the relevant server - that can be an issue in a shared environment - but talk to the hosting provider on that.
