This is a simple example that shows how to receive notifications about data becoming available using a Query Condition. QueryConditions use the same SQL-based filtering syntax as ContentFilteredTopics for query expressions, parameters, etc. Unlike ContentFilteredTopics, QueryConditions are applied to data already received, so they do not affect the reception of data.
