Exclude Condition in set analysis

[Shoban_01]

what is a different between  

Count ({<Country =,year={'2015'}>} Client_ID)

and 
Count ({<Country ,year={'2015'}>} Client_ID)

and 

Count ({<Country -=,year={'2015'}>} Client_ID)

All three expressions are effectively the same. They all count Client_ID using a selection of year=2015. 

They all ignore any selections in field Country. They use different syntax to do so, but the effect is the same. 

I believe the preferred syntax is "Country=".

You are right. The 3 expressions bring the same result. Sorry.
