QPL is a Groovy-based Query Processing Language. It can be used to create complex query structures from multiple inputs, such as security constraints, user interface controls, and other information about the user or search environment. It is also a good choice for creating queries which have complex relevancy ranking requirements.

The QPL product is not part of the Aspire Content Processing product and licensed under a separate agreement. If you haven't yet read the introduction to QPL, it's here.
