For some time now, you could search for PDF files with Boolean terms or by using PDF specific search engines like, Data-Sheet, Pdf geni.com and pdf Search Engine. Sites like Scribd and the defunct DocuFarm have also taken steps, along with PDFoo.com, to make searching for PDF files a one-stop journey.
But despite this convenience and ease, PDF searches have been exclusive only to native PDF files, which have been made specifically from digitally created documents (as opposed to paper documents being scanned in to make a PDF file). Well, last week
Google announced they were making scanned PDFs searchable by using OCR technology to make the text in the PDFs indexable.
