Hi,

I want to search for a particular text(Ex : Clinician Code) in the PDF which is in Encoded Base 64 format.

Can it possible to read and filter the text and please provide a sample code for this?

Thanks for your time to help on this!

Converting the Base64 stream to a pdf is trivial, extracting and searching text inside a pdf....can be hard to (almost) impossible.

It's tricky but not impossible, but obviously not in ObjectScript. Requires additional tools, which should be plenty, now with Python Embedded, it should not be an issue, even with image-based PDFs, which will require OCR.
