I tried this on one of our lists as follows
 
query LSN with topic:LEA
 
but it returned a response stating in part
 
>The WITH list is unknown to [log in to unmask] Your request is
>being     forwarded     to      the     nearest     backbone     server,
>[log in to unmask]
>
>The TOPIC:LEA list is unknown to [log in to unmask] Your request
>is    being     forwarded    to     the    nearest     backbone    server,
>[log in to unmask]
 
Did I get the syntax wrong?
