I have two pdf files:

* **original image pdf** *where the pdf file is just an image of the text*
* **ocr pdf** *produced by OCR, using [ABBYY FineReader](http://www.abbyy.com/finereader/) 11*

these are the process i did 

1. i have a image pdf then i use abby to perform OCR function
2. then i convert my pdf to scanble pdf in abby transformer 3.0
3. then i compare both the source file and ocr file using acrobat but all those hyphens are in error how to skip those hyphens while searching ?
