Query Filter Conundrum

customaware

I have 3 BOs.

Object A
Object B
Object C

Object B Owns Multiple Object C
Object C has an attribute that is Single Peer Object A

Having Object B in context, I want a Query to display all Object A that are NOT in any Object Cs that are owned by Object B

I am going down the path of...

FIND Object A WHERE NOT(Object B CONTAINS ANY Object C WHERE Object C.ObjectA = Object A )
Note... this is not an actual action... it is just pseudo code to explain what I need.

Any ideas would be appreciated.

Worked it out....

With Object B in Context....

FIND Object A WHERE COUNT Object C WHERE (Object C.Object A=Object A AND Object C.Object B=Object B)=0
