This section applies only to the EP Enterprise Edition;
that is, the search portlets are not available in the Demo or Information
Edition of EP.
This document describes the search portlets that are available in Enterprise Portal. You can use these portlets to execute actual searches. The search portlets can also be used as examples to create your own search portlets or to customize the search portlets provided with EP.
Enterprise Portal uses a search engine—the Dynamic Reasoning Engine (DRE)—to perform concept-based searches. EP provides six search portlets implemented as JavaServer Pages (JSPs) that access the DRE via the Portal Search Enterprise JavaBean (EJB). These search portlets allow you to execute a single search across multiple databases and display the combined results to the user.
