The rule form is a section of the query editor in the Configuration Tool where a configurator can specify a query using the rule language. It can be used for queries that are too complex to be defined in the simple form. For example, a query in the rule form that finds all members over 16 years old and lists them in the alphabetical order may look like this:

FIND Member WHERE Member.Age > 16 ORDER BY Member.LastName 

This particular example can also be specified using the simple form.
