and submit the same query to server Y and have it not succeed because server
Y doesn't index the same properties as server X.  Is this correct?  Or would
it be the case that both queries would work, but the query on server Y would
be much slower because the searched property isn't indexed?

My concern is with interoperability.  If it is the case that the same query
might not work from server to server, it will be very difficult to develop
clients that use searching, and could lead to lack of adoption of the
