Query
=====
For the Query Protocol, the user will send messages of the format: <tt>[field1]=[search1],[field2]=[search2],?=[search3]</tt>, where <tt>field1</tt> and <tt>field2</tt> are Name components, <tt>?</tt> indicates an autocomplete search, and <tt>search*</tt> is what to use for searching on. <i>(See [[Schema]])</i>
In response, the Query backend of the Catalog will make Data available that includes a list of names that match the query.
