Enabling Siebel Search requires setting up a server to act as a Search server. This server will contain both the Siebel Server and the Hummingbird SearchServer. Indices should physically be located on this machine. Searches done from the Web client can be done directly on the URL corresponding to the Search server or through another Siebel Server. In this case, the Siebel Server would pass the search execution request through to the Search server. Administration, performed from the Web client, must be performed on the Search server and not remotely through another Siebel Server. Mobile Web clients have the option of synchronizing the indices from the Search server onto a local machine. In this case, Hummingbird is required to be installed on the Mobile Web client to enable search execution.
