Siebel Search uses Hummingbird SearchServer 5.0, the successor product to previous Fulcrum versions. For information about which versions of the Windows operating system are supported by Hummingbird SearchServer, see the system requirements and supported platforms documentation for your Siebel application.

CAUTION:  The Hummingbird SearchServer 5.0 server should be installed on the designated Siebel Server before any Siebel software installations can be performed.

Make sure that the following requirements are met before you begin the installation process:

• You must have administrator permission for the machine on which you will be installing Hummingbird. For information on setting up appropriate permissions for installation, see the Siebel Server Installation Guide for the operating system you are using.
• If you plan to have very large indices (or frequent searches and indexing), you should use a dedicated Siebel Server.
• Make sure that you have enough disk space for the indices. When the indexing engine is run, two sets of index files exist until the final sort file is merged with the existing dictionary and reference file. Until a single updated set of index files is generated, temporary space requirements for indexing can be two to four times the ultimate size of the index files.
• The Search server machine must have client connectivity to the database.
• You must determine where the shared document indices will be kept, create a share name for the location, and give all users read access to it.
• The Web Server, Siebel Server and Fulcrum Server may be installed on independent machines.
