If you are in a z/OS environment, use ARSPDUMP to dump the PDF text and find out the locations on the pages of the text you need.
But PDF load to CMOD on z/OS is time intensive, and works best from Windows index servers.
We now process 100+ PDFs in our bill nightly, from Windows up to z/OS, it take 5 hours on 8 servers, with about 18 minutes dedicated to indexing, and a 90 second upload. In CMOD 8.4.0.3, we get a 16 fold increase in file size from 30 Mb to 500 Mb, and get about 18% compression from OD77.
If you'd like to know more about our experiences with PDFs in CMOD, drop me a line.
