If you are using Oracle Endeca Commerce for your site search features, install and configure either Oracle Endeca Guided Search or Oracle Endeca Guided Search with Experience Manager as required. It is highly recommended that you have a running Endeca installation in place before you install your ATG products so that you can enter appropriate Endeca-specific information in CIM when you are configuring your other applications. Refer to the Oracle Endeca Commerce documentation on the Oracle Technology Network for more information.
