      In our MongoDB-CSharp driver we convert code expressions like that to documents queries.

      !(Address.IsDefault && Adress.Name=="foo")

      The problem here is that the ! operator reverses the meaning of both equality checks. This scenario would be much easier to accomplish when we could use the $not operator like the $or operator.

      Example:

      { $not : [ 
    { "Address.IsDefault" : true },
    { "Address.Name" : "foo" }
] }

      I think also that this is more the way the users expect to use the $not operator.
