The Endeca Application Controller (EAC) is a control system you can use to control, manage, and monitor components in your Guided Search implementation.

The EAC provides the infrastructure to support Guided Search projects from design through deployment and runtime. It replaces the deprecated Control Interpreter, while leaving the Guided Search tools (Developer Studio and Workbench) largely intact.

The EAC uses open standards, such as the Web Services Descriptive Language (WSDL), which makes the Application Controller platform- and language-independent. As a result, the Application Controller supports a wide variety of applications in production. It allows you to handle complex operating environments that support features such as partial updates, delta updates, phased MDEX Engine updates, and more.
