I have a bunch of PDFs that have been through an OCR process. I don't believe they're being indexed in my existing search results. How do I add these folders to the search indexer, and additionally tell the indexer to index the contents of the files?

Just press the Win+W from the desktop and type index.

enter image description here

now select the option Indexing Options a windows will appear and select the Advanced option from there, now another pop window will appear and select the tab File type. Now search the .pdf file and select it and select the option Index properties and File content and press Ok button.

Which is, incidentally, exactly the same process as on Windows 7 or Vista. Unsurprisingly, I might add. – Joey Oct 27 '12 at 16:35
@Joey go ahead. – avirk Oct 27 '12 at 16:38
Thanks avirk. @Joey, it's nice to see some things haven't changed w/ the new OS. :-D – Nathan DeWitt Oct 27 '12 at 16:40
Well, they only have so many resources so changing things that work and are only used by a very small minority of users and not even on a regular basis isn't so high on their list; after all, there are costs :-). Cf. the font installation dialog which remained unchanged from Windows 3 up to Vista, I think :-) – Joey Oct 27 '12 at 16:46

This is a multiple step solution.

  1. Win-x, then select Control Panel
  2. Search for search and then Select Change how Windows searches under Indexing Options search - Control Panel
  3. In the Indexing Options dialog, select Modify Indexing Options
    and add any desired folders in the Indexed Locations dialog box. Indexed Locations
  4. To ensure the contents of the file are indexed, click Advanced in the Indexing Options dialog. Click on the File Types tab and ensure the pdf extension is checked and the Index Properties and File Contents radio option is selected.
    Advanced Options
  5. In my example, the Filter Description reports "Registered IFilter is not found". I downloaded and installed the Adobe PDF iFilter 9 for 64-bit platforms from Adobe.
  6. Now the Filter Description reports "PDF Filter".
    Advanced Options with Filter.

If you don't use Adobe's Reader, there are 3rd party PDF iFilters available as well, such as this one from Foxit. – Karan Oct 28 '12 at 0:49
