Yes, but there was no way to say , give me all the stuff from this date 
to this date, in an inclusive fashion.  My understanding was that you 
could query by date, but only with a single request per.  In other words 
you needed to know the date ahead of time vs having an indexed data 
source to retrieve from.  This would make life much eaqsier for query 
building functions based on grouped returns.
