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.
