Absolutely agree!

Actually I am not sure what the problem actually is.  Does OP want to
return all objects which are in both Arrays?  Does he want to return
all objects which share a particular set of properties?  etc.  Before
we can provide solutions we have to know what problem must be solved.

Kind regards
