. When a more selective retrieval is needed, JDOQL (JDO Query Language) is used. JDOQL for JDO is like ... "this.verified" is a valid query filter. It selects all the objects with the true value in that field

one by one. If more selective retrieval is needed, a Query can be used to retrieve only objects

(what is known as "a man in the middle attack"). The server, on the other hand, might be less selective
