 another, which can be harder to read. So when you tell RT to display a lot of
 columns, it's usually worth adding a well-placed NEWLINE.
 
+Let's say, for example, you have a custom field named 'FlightBooked' that takes
+the values, 'true' or 'false'. If you were to search for all tickets that do not
+have the custom field value, 'true', this would results in a list of tickets with
+the value 'false' and (no value). In order to make sure that custom fields that
+have no set value are not included in the your search results, add the following
+to your query:
+
+AND CF.{'FlightBooked'} IS NOT NULL

 And there are the basics of the query builder! To implement these basics to
 build reports, please see the Dashboard & Reports document. For definitions of
 piece of RT metadata, please see the Definitions of Ticket Metadata document.
