The problem that that in most cases I've come across the PDF is protected and does not allow text-extraction. Though this could be theoretically worked around, it's not really allowed afaik.

Also there is an issue for this already:
http://issues.apache.org/jira/browse/NUTCH-290

The problem that still needs to be worked around imho is that no text should be shown instead - and I'd which a clarification why currently we the raw binary data is taken as summary.

PS: Next time please search before opening a new issue. (Meant just as information, not to make anybody angry ...)

I searched before but solution was not there alternative you have given and if you know any pdf properties that have to change then let me know

Thanks

I think NUTCH-338 will fix this problem, since the "garbage" seems to come from the text-extractor.

The most common cause of this is a PDF that uses subset fonts. Short of OCR there is nothing we can do to recover the text.
