This is the process for running OCR on a PDF so that it is searchable:

1. For most PDFs, you want to run Optimize after you scan them. First rename the file; then pull down the Document menu and select Optimize. - Then, to run OCR: open the PDF file you want to run OCR on. - Pull down the File menu, choose “Save as,” and add “-ocr.pdf” to the file name - Pull down the Document menu, point to “OCR Text Recognition,” and then point to “Recognize Text Using OCR…” and “start” - The OCR process will start. It will take some time, depending on the number of pages in the PDF. - When it finishes, save the file. Be sure to check by doing a search on “the” or another word in the file and make sure it returns results.
