I learned that is possible using M. Explorer search for pdf files that contain "/Text" and as results you can identify with file are searchable or not (OCR).
That's NOT a reliable method.
It may work in 80-90% of all documents, but it is NOT a 100% guarantee...
One of the reasons for this is that PDFs support "incremental update" - meaning that newer info can replace old WITHOUT removing it from the file!
Question: is there any similar character that I could search to identify the page format (A4, A3, etc) in a pdf file without opening it.
First, each page in a PDF can be a different size.
Second, page sizes are defined in "coordinate space units" - which you would need to convert to standard sizes in inches, cm, etc.
Third, as noted above, incremental update would effect the results of your search.
