searching in OCRed pdf

[Péterfi Balázs <b....@i-deal.hu>]

Hello,

I'm developing an application that uses jackrabbit and have some problem 
with searching in pdf files. When I search in a pdf that was generated 
from a word document it works. When I try to search in a pdf that has a 
scanned document inside it and I can search through its contents from 
within Adobe Reader (some sort of Optical Character Recognition) but my 
application does not obtain results. I don't know how does this kind of 
pdf work but I need to search in it. Does jackrabbit support it?

Thank you!
Balazs

Jackrabbit PDF text extractor uses PDFBox. If Adobe Reader can search
the text then PDFBox should be capable of extract this text, but I
only is my opinion.

I think it has already OCRed because as I wrote I can search in the pdf 
with adobe reader and it also selects the result. But what I see is a 
scanned paper and I guess there is a text layer "behind" it. Is it possible?

You can make a text extractor which perform an OCR.
