Find and Fix PDF Files That Lack Searchable Text

Archiving paper documents as PDF files is a great way to save shelf space and preserve essential records.

However, more than simply scanning the documents is required. It would be best if you also used Optical Character Recognition (OCR) to process the scans. Once OCR has processed a PDF scan, the file contains an invisible text version in addition to the scanned image of the document. macOS Spotlight can now index the content, and you can use HoudahSpot to search your document archive.

But what if some of your PDF files lack OCR text?

Customize Your HoudahSpot Search Setup

In HoudahSpot, you can choose between hundreds of criteria to search for files. HoudahSpot also lets you specify in which folders to search and how to sort results.

There are lots of options to choose from – and settings you don’t want to make over and again.

Search criteria, results display, and sort order are a matter of personal preference and habits. You may, for example, find yourself frequently searching for files by file extension. You may prefer to search your full hard drive rather than just your home folder. You may want search results always to list file size.

Quick Access to HoudahSpot Search Templates

In HoudahSpot, search templates serve as starting points for searches that you perform repeatedly.

HoudahSpot comes with a set of sample templates. These include, for example, a template for finding photos. This template is set up to search for image files having a resolution of at least 7 MP. Search results show image previews. The Refine pane is pre-configured for searches by camera make and model, ISO speed, and flash settings. To find photos you just need to fill in the blanks and start the search.

Templates can also act as dynamic file lists. The Recent Files template, for example, lists files used or modified within the last 7 days.

You will certainly create your own templates or customize the sample templates to fit your needs. You may, for example, want to update the My Photos template to search only for files matching your camera make and model.

As templates become a central part of your workflow, you will want quick access to your favorite ones.

Find PDF Files That Need OCR Processing

There is an updated version of this post.

Scanning paper documents to PDF files lets you archive important (and not so important) documents without filling up cabinets.

Optical Character Recognition (OCR) makes these scanned documents much more useful than their paper originals. Once a scan has been processed by OCR, the PDF file contains both an image of the document and an invisible text version. The text can then be searched using HoudahSpot.

Unfortunately, you will find that not all of your PDF files have text content. You may have forgotten to run them through OCR. Or you may have received the scanned document from someone else.

How can you find these files and rectify this?

With a little trick, HoudahSpot can find PDF files that lack text content. It is safe to assume that any text contains either a space or a period. Thus, we will be looking for any PDF file that contains neither space or period.

This translates to the following search:
