Are you actually seeing a limit? My experience is that PDFs with huge numbers of pages wind up with very big in-memory xref tables, and that can consume quite a bit of memory - but if you have enough memory, then there isn't any practical limit that I'm aware of.
Some things you can do to reduce memory usage: Open the PDF in partial mode Use the latest code in SVN (I recently added a bunch of optimization code for working with super large files) If you do run into memory issues, you might find that you can work around them by processing some number of pages at a time, then re-opening the PDF (in partial mode!), and processing the next chunk of pages. This will effectively purge out unneeded xref entries. You'd probably be looking at chunks of 10-50K pages or so, but do some testing to see where the garbage collector starts to get bogged down and go from there. It's not possible to search a PDF without first extracting it's contents. If you don't want to do a linear search, then you should index the text you extracted. iText isn't going to help you here - something like the Lucene project is what you are looking for.
