I have one of my text books for school as a .pdf file and any term I put into find yields no results, even words like "the" don't come up. I am able to search most other documents I have tried and even the same document using the .pdf reader on my phone. Is there anything that could cause Reader problems? The book is around 1300 pages if that makes any difference.
Edit: I just installed both Nitro Reader and Foxit Reader, they both were able to search the document with no problems at all.
Thanks for any help!
