The option to skip pages with text using DCC will depend on which application you are using to call DCC. If you are using the Web Client, this option is something you can toggle when you are scheduling OCR on a document. When you have a document selected, you should be able to find the option to “Generate Searchable Text” from the toolbar. Choosing this option will open a dialog box with the option to generate text for all image pages, specific pages, or only on pages without text.

If you are using Workflow, the option to skip pages that already have text is not currently available for configuration from the Schedule OCR activity, but the Laserfiche development team is looking into adding it in the future. In the meantime, you may be able to work around this using searches to locate the documents you need to OCR. For example, if you would like to find all documents with pages but no text associated, you can use the following query: {LF:AssociatedPages="Y"}&{LF:OCR="none"}.

I have implemented a WF that sends to OCR through DCC when any new documents were either created or modified for that day and the OCR status is either NONE or SOME.

In the OCR setting on the Windows Client, there is an option that says to OCR "All image pages without text". I, however, don't see that option available in the DCC options in workflow so anytime there is a new page being added to a document, the whole document gets OCRed again.

The main issue is that lots of documents with hundreds of pages get OCRed completely again and again and again... and this slows down the OCR process for nothing. The reason why that same document goes back to OCR is because these documents get new pages added many times for a few months, thus, OCR need to be run so often on the same document.

Is there an option I have not seen?, or a hidden option?, or does this require Laserfiche to add this as a feature request as it was said earlier in this post?
