Moderator has tagged the following question
which has nothing to do with my original question, because i have asked how to do a wildcard search within the pdf file, and the tagged question is about how search for pdf file using RegEx,which is entirely different from my goal/question .
The concerned mod says that "how to use a specific software to solve a problem" is off topic but i literally see hundreads of high rated question asking ideas to solve problem with a software for example
to name a few.
and moreover the question is marked as duplicate, mod says its off topic, im really confused here. could someone clarify about this pl.
