         Depends on what the queries are ;).

         That can't be done at the libpoppler level.  You would have 
to create a custom OutputDev and run that - low level Xpdf.

         ASSUMING that info is in the PDF - you can get that from libpoppler.

         Poppler has no support for PDF writing/modification.

         Won't know till the annotation support is implementated.


         In the meantime, there are other tools/libraries out there 
that you could use to get that information (and more).
