A Closer Look at How to Set up a Parsing-Only Workload - comment by carrie

Geeta,
 
If you are sure that every user has a profile, then there is no down side of including Profile =  * in your classification.   It is only a problem if a user has no profile.  In that case, any query coming from that user will never classify to a workload that says Profile =  *.
