Why is XPDF missing words and files when extracting text from pdf files?

Hello all,

I have a search engine that runs on our website server.  It uses an inverted index created by an indexing routine.  In order to index PDF files, the indexer calls the utility XPDF ( ) to extract the text.

Mostly it works just fine, BUT:

- sometimes it misses words.  For example, if a PDF document is konwn to contain the phrase "blue sky", after indexing a search may find "blue", but not "sky"

- sometimes it skips files completely.  This seems to be accompanied by cryptic error messages like "Bad Annotation".

Anyone have insights into XPDF?

I do not have any previous experience of XPDF.

Have you tried contacting the software authors?  Perhaps there is a fault with it that they are not aware of.

You may also like to extract your PDF based text into other formats using these tools:

RTF, MS-Word DOC, or Text (TXT):

Well, although it doesn't actually answer the question, I guess I'll have to award the points by default.

You could have waited for further Expert input; you need not have closed the question at all.

Did you contact the software vendor?
