        We use this merge only when the explicit arg criteria is passed to the clients.
        The idea is to check if this has to be merged with the initialCriteria or not.

        So the default return is always argCriteria, in case the initial criteria is null!

        So when useInitialCriteria is true, the initial criteria defined will always be used, no matter what,
        it is a predicate and. (Not to be confused with or)
