I scan documents (receipts, etc) PDFs and the software does OCR to make them searchable. I can search them from within Preview, but I'd like to be able to search within the documents in Finder (or Spotlight). Is there a way to do this? Or a third-party app that does it?
There is a free app, EasyFind, that will let you search files. Its available from the app store. It has a fast search engine and you can select where to search. Click the setting button on the top left to select which file extension to search in.
It actually seems like Spotlight already does this. Sorry for the point less question!
