Document revisions still showing in Global Search although Documents Module is restricted

For my sales person role, i have set below rights on documents. yet when the sales person searches for a document Name, it still get displayed on the Advanced Search .

There are no rules for the Document Revisions module so maybe this is the issue? Anyone?

Can i modify UnifiedSearch Query in upgrade safe way? If not, can we show the records only assigned to current user?

Funny, somebody just opened an Issue today with this same problem, but for Elastic Search
