In response to "Rush Limbaugh, computer genius" by mara

FWIW, if a pdf is a scan of a paper copy of a document, then it can not, in fact, be keyword searched.

I don't know if that is true for the document he is discussing.

Can't a Microsoft Word document be converted to a PDF, and the text then be searchable? - JaxSean Feb 18, 09:12
We have scanned versions of historical books that can be keyword searched. -- (link) - mara Feb 18, 09:10 1

  - OCR would do this. Not terribly special, many places use it, but certainly not everywhere. -- nm - Subversive Feb 18, 09:09

- a scan is an image. Image data cannot be searched, unless you run an OCR algorithm on it. Some scanners have that built-in, some don't. -- nm - Beryllium Feb 18, 09:09
- and whether or not it's OCRed, I would imagine. -- nm - znufrii, cliqueless Feb 18, 09:08
- and also correct. depends on the quality of the scan -- nm - Jovian Feb 18, 09:08
