Whether the historical news under each RIC for the same company is the same?

A further question is whether any of the RIC for the same CUSIP would return the same list of historical news. I'm using "BestMatch = False". Thanks.

Thanks, Alex. I also ask a question under that thread. Could you help me with the question? Basically, I'm wondering how I could get the Primary RIC when I set the BestMatch = False.
