Hallo Michael, if you want to make a request synchroneously then "get" is the correct choice.
If the kind of query would be of lets say the kind: a) "Give me back the last 5 messages of a particular topic" or b) "give me all messages since Christmas for a given topic" It is what we call history queue queries, that is, queries regarding a specific topic (a specific msg oid). These are on our high priority list and will be implemented as a plugin. Fore more exotic queries one can then write a more specific plugin. For case a) there is already a way of doing it. See the requirement: http://www.xmlBlaster.org/xmlBlaster/doc/requirements/interface.subscribe.html for an example or have a look at HelloWorldSubscribe.
