Timo Boehme commented on TIKA-93:
---------------------------------
Hi Anurag, which PDF are you referring to? Without knowing the size, page count
and structure of the pages it is hard to say what is going wrong. For instance
it could be as I already wrote in my last comment that the pages contain a
large number of images (e.g. one per word or chunk) instead of a single one per
page. Try to print the PDF to images (one per page) and run this through
Tesseract.

> command line OCR tools like Tesseract
> (http://code.google.com/p/tesseract-ocr/) that could be invoked by Tika to
> extract text content (where available) from image files.
