Matching percentage from mutiple PDFs in IDM document profile

Hello:

I have multiple business areas that I create IDM and EDM policies. Specifically with IDM, I will occassionally receive several PDFs that are part of a collection for a Play Book that a business unit will use during the year. The response rules operate perfectlty but my questions is surrounding the indexed pdfs themselves.

What would be the best practice in this instance?

(I think I already know the answer but I want to verify with a SME)

Question:

When you create a new IDM document profile with multiple files within the zip file, does the match percentage apply to all of the documents individually in the zip or does the policy apply the match percentage against all the files as a whole profile?
