All tasks are instantiated and managed by the agent as you say.
When you do a query like this QMF uses AMQP to send a message to all
agents requesting that each agent return all object IDs for objects that
match the given criteria.  

The criteria at this point are all just AND'd together.  However hopefully
we will have more powerful search ability soonish.. things like OR's and
regular expressions etc.
