Adobe have provided a web site at

http://searchpdf.adobe.com/

Which

1.    Allows you to search the content of PDF files on the web.
YA search engine but dedicated to the contents of PDF files which makes it
unique AFAIK.

2.    Make your own PDFs of a website or document FOR FREE.
This is a trial system and will quite possible stop being free in due course
(as it competes head on with their Adobe Acrobat product).
