PDF issue

[VaibhavDS19]

Hello, I have multiple PDFs and I convert them from pdftotext library, I have 2 questions:

1. QA: If I pass the entire PDF object it shows unknown whereas checking each page shows the correct result i.e for page in pdf works if page is context for QA whereas pdf itself as the context shows 'unknown' as result
2. Is there a way to use multiple docs/PDF in some way and generate the result based on the most likely answer?
