Carrying out an Search (Audit) on whose accessed a SharePoint document (Excel, Word, etc,)

Hi LeonPavesic

Thank you for your reply.

I haven't be assigned an E5 license.  This is being requested

I've entered the criteria search information 

The field with the red crosses, I've entered the folder name, Sub folder name.  Inserted the folder, sub folder and for a single excel document in there but no results are returned.

This is the folder an audit is being carried out on

There are 17 sub folders and each one will have multiple excel documents.  I need to see who as viewed / accessed them

There 

Can an audit be carried out for an entire folder??
